Flask vs FastAPI: Which is Better for Deploying ML Models?

Posted on July 2, 2025July 2, 2025 by Imarticus Learning

Getting machine learning models out there for people to use is a big deal. Data scientists pour their hearts into building amazing models. But what’s the point if no one can actually access them? This means putting them into action.

Users then get to interact with them. Picking the right web framework for this is super important. Two really popular ones are Flask and FastAPI. We’re going to take a good look at both right here.

If you are eager to truly master data science, you should certainly consider enrolling in a program in data science and artificial intelligence. But, if you’re looking for a basic article to help you figure out which one between FastAPI vs Flask fits your needs best, this is the one.

Why Put ML Models into Action?

Models exist to give predictions. That’s how they become genuinely useful. Businesses rely on these predictions every day. This is how they create real value. Deployment makes models available to everyone.

They live on a server, ready to go. Users send their requests. The model then quickly gives back answers. That’s the whole point, isn’t it?

A Bit About Flask

Flask is what we call a micro-framework. It’s incredibly light. Developers really like its straightforward nature. You can get something up and running with Flask super fast. It gives you just the basics.

You then add whatever else you need. This gives you a lot of freedom. Lots of projects use Flask. It’s a very reliable choice.

A Bit About FastAPI

FastAPI is pretty new on the scene. It’s made for speed, pure and simple. It uses some of Python’s most modern features. Handling multiple tasks at once, called asynchronous programming, is a core part of it. FastAPI even writes its own documentation automatically. This saves so much time. It’s getting more and more popular. Many folks are using it for building APIs.

FastAPI vs Flask: What’s the Real Difference?

There are some big differences between them. Flask works in a synchronous way. FastAPI, though, is asynchronous. This really impacts how fast things run. Flask needs more setup if you want to build APIs. FastAPI, on the other hand, comes with API features already built-in. It uses something called Pydantic for checking data. Flask doesn’t do this by default.

Performance Really Counts

When you’re putting ML models into action, how well they perform is everything. Models can be quite heavy. They might take some time to process things. The framework you choose shouldn’t make things slower. Requests need to get quick responses. Users expect things to be fast. This is truly vital for any application.

FastAPI vs Flask Performance: A Closer Look

Generally, FastAPI offers better performance. Its asynchronous design really helps and can handle many requests all at once. It doesn’t just sit and wait for one task to finish, but moves on to the next. This makes it super efficient. Flask, however, processes requests one by one. It might struggle a bit when things get busy.

Imagine a prediction scenario where a user sends in some data. The model gets to work on it. Then it gives back a result. If many users send data at the same time, a fast framework is a lifesaver. This is exactly where the FastAPI vs Flask performance comparison really shows itself. FastAPI clearly shines in these situations.

Feature	Flask (Synchronous)	FastAPI (Asynchronous)
Request Handling	One by one	Concurrent
Speed	Good for smaller loads	Excellent for high loads
Built-in Features	Minimal	Rich (API docs, validation)
Learning Curve	Lower	Moderate

Building with Flask and FastAPI

Flask asks for less code to get started. You set up your routes, and write functions for them. It’s really simple to grasp. For smaller models, Flask works just fine. If you don’t expect a lot of requests, it’s good and beginners find it easy to learn.

FastAPI uses something called type hints. This makes your code very clear. Pydantic checks all your data. It makes API development quite simple. Asynchronous functions really boost speed.

For more complex APIs, FastAPI is better. It even creates its own documentation using Swagger UI.

FastAPI vs Flask: API Documentation

FastAPI automatically makes API documentation for you. This is a massive plus point. Developers can easily see all the endpoints. They can even test them out right there. Flask needs you to add other libraries for this. You have to put them in yourself which is extra work. For big teams, automatic documentation is a must-have. You can learn more about API documentation on.

FastAPI vs Flask: Data Validation

FastAPI relies on Pydantic. It makes sure your data is correct. Any incoming data gets checked. This stops errors from happening. It makes your API very reliable. Flask doesn’t have this built-in feature.

You have to add validation yourself. That means writing more code. This is definitely an advantage for FastAPI.

FastAPI vs Flask: Concurrency and Doing Things Asynchronously

This is a fundamental difference. Flask uses something called WSGI. It handles one request at a time per worker. FastAPI uses ASGI.

It can handle many tasks at the same time. For tasks that involve waiting, like reading from a disk, this is crucial. ML model inference can often involve waiting. Loading model weights, for example, takes time.

Think about it like this: Flask waits for each step to finish. FastAPI, however, can do other things. While one model is loading, another can be busy predicting. This way of doing things in parallel is incredibly powerful. It significantly increases how much work your application can get done.

Conclusion

Your choice really comes down to your project. For small, straightforward APIs, Flask is a fantastic starting point. It’s super easy to use. But for ML model deployments that need to be fast and handle lots of users, FastAPI is the clear winner. Its asynchronous nature and built-in tools are truly outstanding. It delivers speed. It provides reliability.

Imarticus Learning offers some really great courses. One of them is the program in data science and artificial intelligence. It helps you build exactly these kinds of skills. You can learn how to deploy models in a very effective way.

So, to sum it up, for modern ML model deployment, FastAPI is often the better pick. Its speed and features are truly hard to beat. However, Flask definitely still has its place for certain kinds of projects.

FAQs

Is FastAPI harder to learn than Flask?

FastAPI is a bit tougher to get started with due to asynchronous programming and type hints, but it makes complex projects much clearer.

Can I use Flask and FastAPI in the same project?

You technically could, but it’s not really common. People usually stick to one main framework for their API.

Does FastAPI mean Flask is no longer needed for anything?

Not at all. Flask is still excellent for simpler web applications, quick prototypes, and projects where top-tier speed isn’t the main goal.

How does FastAPI vs Flask performance look in tests?

Tests consistently show FastAPI performing better than Flask in terms of how many requests it can handle per second and lower delays, especially when lots of people use it at once.

Which framework is better for building smaller, independent services?

Both can work well, but FastAPI’s speed and structured API design make it a very strong choice for building efficient microservices.

Are there any specific code libraries that work better with one framework?

Most machine learning libraries don’t care which framework you use. But FastAPI’s Pydantic integration is fantastic for making sure your input and output data for ML APIs is correct.

How can I make sure my application is always available with either Flask or FastAPI?

You can use tools like load balancers, run several copies of your application, and use containers (like Docker and Kubernetes) to keep both Flask and FastAPI applications running smoothly.

K-Means Clustering Explained: A Beginner’s Guide with Python

Posted on July 2, 2025July 2, 2025 by Imarticus Learning

Have you ever looked at a massive spreadsheet and thought, “How do I even begin to group these customers, users, or patterns?” You’re not alone.

For data analysts and beginners stepping into machine learning, understanding how to organise unlabelled data is frustrating. You don’t want theory-heavy explanations. You want a hands-on approach that’s simple, practical and shows real results.

That’s exactly where k means clustering fits in. Whether you’re building recommendation systems, segmenting customers, or detecting anomalies, k means clustering algorithm simplifies complex data by breaking it into logical groups.

What is K Means Clustering and Why Does It Matter

K means clustering, which is a vector quantisation method first used in signal processing. It partitions n observations into k clusters, where observation is basically assigned to the cluster with the nearest mean (also called the cluster center or centroid), which acts as the cluster’s representative.

You tell the algorithm how many clusters (or “groups”) you want. It then:

Picks some initial points (called centroids),
Assign nearby data points to those centroids,
Repositions the centroids based on the average of the assigned points,
Repeat until nothing changes.

It’s clean, fast, and widely used, especially in marketing, finance, and recommendation systems. If you’ve ever used YouTube or Amazon, you’ve already seen this in action.

The k means clustering algorithm works best when the data naturally falls into separate groups. It’s used across sectors, from banking to telecom, where decisions need data-based segmentation.

Choosing the Right Number of Clusters

A common question: how many clusters do I need?

The answer? Use the Elbow Method.

The algorithm calculates “inertia” and how spread out the points are in each cluster. The more clusters you add, the lower the inertia. But at some point, adding more clusters gives very little improvement. That “elbow” point is your sweet spot.

This is why many analysts plot inertia versus k. The curve tells you when to stop. In a Programme in Data Science and Artificial Intelligence, you’ll often use this graph before running any model.

K-Means in Action: A Simple Python Example

In cluster analysis, the elbow method helps decide how many clusters to use in a dataset. You plot the explained variation against the number of clusters, then look for the ‘elbow’ point where the curve starts to flatten. That point usually shows the best number of clusters.

Let’s walk through a basic k means clustering example using Python:

from sklearn.cluster import KMeans

import pandas as pd

# Sample dataset

data = {‘Income’: [15, 40, 90, 55, 75], ‘SpendingScore’: [39, 81, 6, 77, 40]}

df = pd.DataFrame(data)

# Running the algorithm

model = KMeans(n_clusters=3)

model.fit(df)

# Add cluster labels

df[‘Cluster’] = model.labels_

print(df)

This code assigns each customer into a group based on how much they earn and spend. Easy to follow. That’s the power of k means clustering with Python, it lets you build results fast.

When Should You NOT Use K-Means?

While it’s a great tool, k means clustering algorithm has limits:

Doesn’t work well with non-spherical clusters.
It can break with too many outliers.
Needs you to guess the value of k (though elbow method helps).
Doesn’t perform well if features have different scales.

So, always scale your data (using standardisation or normalisation) before applying it. And test with different k values.

Real-Life Use Cases: K-Means at Work

Retail: Group customers into value segments for personalised promotions.
Healthcare: Group patients based on symptoms or treatment responses.
Finance: Spot unusual transactions that might indicate fraud.
Telecom: Segment users based on usage patterns and churn risk.

Practical Example: Customer Segmentation

Refer to the table attached. It shows a common use case in customer segmentation using a k means clustering example.

With just two features, income and spending score, you can group users into three practical clusters: high-value, low spender, and mid-range. Each decision becomes data-driven.

Customer ID	Annual income (₹000s)	Spending Score	Assigned Cluster
1	15	39	Low Income
2	40	81	High Value
3	90	6	Low Spender
4	55	77	High Value
5	75	40	Medium

Tips to Use K-Means Efficiently

Always standardise your data.
Use the elbow method to decide k.
Run multiple times to avoid poor initialisation.
Don’t rely on it for non-linear problems; go for DBSCAN or hierarchical clustering instead.

These simple tweaks make a big difference in results.

FAQs

1. How does the k mean clustering algorithm work?

The k means clustering algorithm works by first choosing k random points called centroids. Each data point is then assigned to the nearest centroid. After that, the centroids move to the centre of their assigned points.

2. Can you give an example of k, which means clustering in Python?

Yes. A simple k means clustering example in Python, which would be using customer data like income and spending habits.

3. Is k means clustering used in real-world businesses?

Yes. Many businesses use k, which means clustering, to improve customer targeting, detect fraud, manage inventories, or optimise services. For example, banks use it to group clients by risk level, while e-commerce platforms use it to show personalised product suggestions.

4. What is the ideal k value in k means clustering?

There is no fixed k value. The best way to choose k is by using the elbow method. This involves testing different k values and seeing which one gives the best balance between accuracy and simplicity. The ‘elbow point’ in the chart usually shows the right number of clusters.

5. How does k mean used in a programme in data science and artificial intelligence?

In a Programme In Data Science and Artificial Intelligence, k means clustering is a core technique in unsupervised learning. Learners practice real-life projects such as customer segmentation, anomaly detection, and pattern recognition. It’s one of the must-know algorithms in most data science curricula, including the one from Imarticus Learning.

6. Why is k means clustering important in data science courses?

Because it helps you work with raw data without labels, real-world data is often unorganised. K means clustering helps make sense of it by grouping similar entries. That’s why it’s a foundation skill in any Programme In Data Science and Artificial Intelligence, especially when working with business or user data.

The Final Words

K means clustering, which may sound like just another algorithm. But once you use it on your dataset, you’ll realise how powerful it is. It simplifies chaos. It helps you take the first step toward advanced analytics.

Start small. Try out the Python example. Tune it. Visualise it. Then scale up.

If you’re serious about building a future in data science, this is one tool you can’t ignore.

Python Data Types: An Introduction

Posted on July 2, 2025July 2, 2025 by Imarticus Learning

Are you confused about why your Python code keeps throwing type errors? Or why do some variables behave unpredictably while others don’t change at all? The real issue lies in not fully understanding Python data types.

Whether you’re just starting out or diving into a data science course, skipping the basics can cost hours of debugging. This post explains what are data types in python, explains mutability, and helps you use each type the right way so your programs run smoothly and efficiently.

What are Data Types in Python?

Python is a programming language that you can easily use for many different tasks.

If you mess this part up, your program might crash, behave unexpectedly, or just slow you down.

Why you need to know this:

· You can prevent errors by choosing the right type.

· It helps improve your code efficiency.

· Data types make debugging faster.

· Crucial for interviews, especially if you’re applying after a data science course.

· You must understand them to master control flow, loops, or even basic functions.

Understanding Python’s Built-In Data Types

Python became popular because it is simple to use and easy to read. That’s why both beginners and experienced people like using it.

Even in 2025, this is one big reason people choose Python. In data science, people come from many backgrounds. Some are good with numbers, and others know coding well. Python makes it easier for anyone to start learning and building things without much trouble.

Python offers several built-in data types grouped into categories:

1. Numeric Types

int: For integers (e.g., 1, 500)

float: For decimals (e.g., 10.5, 3.14)

complex: For complex numbers (e.g., 4 + 3j)

All of these are immutable data types in python, meaning their value cannot be changed after assignment.

2. Text Type

str: For text or string values (e.g., ‘hello,’ “world”)

Again, strings are immutable. Even if you change a character, python creates a new string object behind the scenes.

3. Boolean Type

Bool: Can be either True or False. Often used in condition checks and logical operations.

Mutable vs Immutable Data Types in Python

Let’s clarify something: many beginners struggle with mutability.

In simple terms:

Ø Immutable means you can’t change the value once it’s set.

Ø Mutable data types in python mean you can change the contents without creating a new object.

Here’s a breakdown:

Python Data Types: Mutable vs Immutable

Data Type	Can You Change It? (Mutability)	What It’s Usually Used For
int	No (Immutable)	Storing whole numbers like age, count, or price
float	No (Immutable)	Dealing with decimal values, such as weight or salary
str	No (Immutable)	Handling text, names, messages, or any string data
tuple	No (Immutable)	Storing a fixed set of items like coordinates or settings
list	Yes (Mutable)	Holding a collection of items that may change, like a to-do list
set	Yes (Mutable)	Keeping unique items without duplicates, like tags or categories
dict	Yes (Mutable)	Pairing keys with values, like name and phone number in a contact list

This comparison will help you avoid mistakes like modifying immutable types or incorrectly assuming you can change them, like lists or dictionaries.

The Different Collection Data Types

1. List – Mutable and Ordered

A list is like a shopping list.

You can add, remove, or change items.

my_list = [1, 2, 3]

my_list.append(4) # This changes the original list

Used when your data will change. Lists are mutable data types in python.

2. Tuple – Immutable and Ordered

Tuples are similar to lists but fixed.

my_tuple = (1, 2, 3)

Useful for data that shouldn’t be changed, like coordinates.

3. Set – Mutable and Unordered

Sets store unique values. Great for removing duplicates.

my_set = {1, 2, 2, 3}

print(my_set) # Output: {1, 2, 3}

4. Dictionary – Mutable and Key-Value Based

Dictionaries are like real-life dictionaries. They pair a word (key) with a definition (value).

my_dict = {“name”: “Rahul”, “age”: 25}

my_dict[“age”] = 26

Very useful in data science course work for structuring data.

How Python Treats Mutability

We visualised the number of common mutable vs. immutable types. This helps you mentally group what’s safe to modify and what’s not. Check the chart for clarity.

Type Conversion in Python

You’ll often need to convert one data type into another:

· str() to convert to string

· int() to convert to integer

· float() for decimal numbers

· list() or tuple() for collection types

Why is this important?

Because mismatched types lead to TypeErrors. You must know which conversions are safe.

Real-world Example: Why Data Types Matter in Data Science

In your data science course, imagine you’re working with a CSV file. If the “age” column comes in as strings (‘25’, ‘30’), you can’t calculate averages. You’ll have to convert it to integers or floats.

Not knowing what data types are in python can lead to major headaches in data preprocessing. That’s why companies expect you to master this first.

Small Errors That Cost Big in Python

Assigning a mutable object as a default argument in a function.
Trying to change an element in a tuple.
Using a string method on a list.

These things seem small but often cause major runtime errors. So be cautious, especially when handling immutable data types in python.

Demystifying Python Operators: Arithmetic, Logical, and More

Posted on December 3, 2024 by Imarticus Learning

Python, a versatile and powerful programming language, relies on operators to perform various computations and manipulations on data. Operators are special symbols that represent specific operations, such as addition, subtraction, comparison, and logical operations. Let us discover the different types of Python operators and explore their applications.

If you wish to learn Python and other essential data science tools and technologies, enrol in Imarticus Learning’s data science course.

Arithmetic Operators in Python

Arithmetic operators in Python are used to perform basic mathematical calculations:

Addition (+): For adding two operands.
Subtraction (-): For subtracting the second operand from the first.
Multiplication (*): For multiplying two operands.
Division (/): For dividing the first operand by the second.
Floor Division (//): For dividing the first operand by the second and rounding down to the nearest integer.
Modulo (%): For returning the remainder of the division operation.
Exponentiation (**): For raising the first operand to the power of the second.

Example:

x = 10

y = 3

print(x + y) # Output: 13

print(x – y) # Output: 7

print(x * y) # Output: 30

print(x / y) # Output: 3.3333333333333335

print(x // y) # Output: 3

print(x % y) # Output: 1

print(x ** y) # Output: 1000

Comparison Operators

Comparison operators are used to compare values and return a Boolean result (True or False). Here are the different comparison Python operator types:

Equal to (==): For checking if two operands are equal.
Not Equal to (!=): For checking if two operands are not equal.
Greater Than (>): For checking if the first operands are greater than the second.
Less Than (<): For checking if the first operands are less than the second.
Greater Than or Equal To (>=): For checking if the first operands are greater than or equal to the second.
Less Than or Equal To (<=): For checking if the first operands are less than or equal to the second.

Example:

x = 10

y = 5

print(x == y) # Output: False

print(x != y) # Output: True

print(x > y) # Output: True

print(x < y) # Output: False

print(x >= y) # Output: True

print(x <= y) # Output: False

Logical Operators in Python

Logical operators in Python are used to combine conditional statements.

And (and): Will return True if both operands are True.
Or (or): Will return True if at least one operand is True.
Not (not): Will return the truth value of an operand.

Example:

x = True

y = False

print(x and y) # Output: False

print(x or y) # Output: True

print(not x) # Output: False

Assignment Operators

Here are the various assignment Python operator types that are used to assign values to variables.

Equal to (=): For assigning the value on the right to the variable on the left.
Add and Assign (+=): For adding the right operands to the left operands and assigning the results to the left operands.
Subtract and Assign (-=): For subtracting the right operands from the left operands and assigning the results to the left operands.
Multiply and Assign (*=): For multiplying the right operands with the left operands and assigning the results to the left operands.
Divide and Assign (/=): For dividing the left operands by the right operands and assigning the results to the left operands.
Floor Divide and Assign (//=): For performing floor division and assigning the result to the left operand.
Modulo and Assign (%=): For performing modulo operation and assigning the result to the left operand.
Exponentiate and Assign (**=): For exponentiating the left operand by the right operand and assigning the result to the left operand.

Example:

x = 10

x += 5 # x = 15

x -= 3 # x = 12

x *= 2 # x = 24

x /= 4 # x = 6

x //= 2 # x = 3

x %= 2 # x = 1

x **= 3 # x = 1

Bitwise Operators

Bitwise Python operators manipulate individual bits of binary numbers. They are often used in low-level programming and data manipulation tasks.

Bitwise AND (&): For setting each bit to 1 only if both corresponding bits in the operands are 1.
Bitwise OR (|): For setting each bit to 1 if at least one of the corresponding bits in the operands is 1.
Bitwise XOR (^): For setting each bit to 1 if the corresponding bits in the operands are different.
Bitwise NOT (~): For inverting the bits of the operand.
Left Shift (<<): For shifting the bits of the operand to the left by a specified number of positions, while the rightmost bits are filled with 0s.
Right Shift (>>): For shifting the bits of the operand to the right by a specified number of positions, while the leftmost bits are filled with 0s or 1s, depending on the sign of the operand.

Identity Operators

Identity operators compare the objects, not if they are equal, but if they are actually the same object, with the same memory location.

Is (is): Will return True if both operands are referring to the same object.
Is Not (is not): Will return True if both operands are referring to different objects.

Membership Operators

Membership operators test whether a value or variable is found in a sequence.

In (in): Will return True if a value is found in a sequence.
Not In (not in): Will return True if a value is not found in a sequence.

Operator Precedence and Associativity

Operator precedence determines the order in which operations are performed. Python operators having a higher precedence are evaluated first. For instance, multiplication and division have higher precedence than addition and subtraction. Associativity determines the direction in which operations are grouped when they have the same precedence. Most binary operators in Python are left-associative, meaning they are grouped from left to right.

Boolean Operators and Truth Tables

Boolean operators are used to combine logical expressions.

AND (and): Will return True if both operands are True.
OR (or): Will return True if at least one operand is True.
NOT (not): Will return the truth value of an operand.

Truth tables can be used to visualise the behaviour of Boolean operators for all possible combinations of input values.

Short-Circuit Evaluation

Python uses short-circuit evaluation for logical operators and and or. This means that the second operand of a logical expression is only evaluated if the first operand is not sufficient to determine the result. For example, in the expression x and y, if x is False, the expression is immediately evaluated to False without evaluating y.

Type Conversion and Operator Behaviour

Python automatically performs type conversion in certain situations. For example, when adding an integer and a float, the integer is converted to a float before the addition is performed. However, it’s important to be aware of implicit and explicit type conversions to avoid unexpected results.

Operator Overloading in Custom Classes

Operator overloading allows you to redefine the behaviour of operators for custom classes. We can customise how objects of your class interact with operators. This can make your code more intuitive and readable by implementing special methods like __add__, __sub__, __mul__, etc.

Frequently Asked Questions

What is operator precedence, and why is it important?

Operator precedence determines the order in which operations are performed in an expression. Understanding operator precedence helps ensure that expressions are evaluated correctly. For example, in the expression 2 + 3 * 4, multiplication has higher precedence than addition, so multiplication is performed first.

How do I use bitwise operators in Python?

Bitwise operators manipulate individual bits of binary numbers. They are often used in low-level programming and data manipulation tasks. For instance, the bitwise AND operator (&) can be used to mask specific bits of a number, while the bitwise OR operator (|) can be used to set specific bits.

What is the difference between is and == operators?

The (is) operator checks if two variables refer to the same object in memory, while the == operator checks if the values of two variables are equal. For example, x is y checks if x and y are the same objects, while x == y checks if the values of x and y are the same.

How can I create custom operators for my classes?

You can create custom operators for your classes by defining special methods like __add__, __sub__, __mul__, etc. These methods allow you to redefine the behaviour of operators for your class objects, making your code more intuitive and readable.

Understanding Missing Values: Types, Causes, and Impacts on Data Analysis

Posted on August 30, 2024 by Imarticus Learning

Missing values in data analysis” refers to values or data that are missing from a given dataset or are not recorded for a certain variable. In this post, we will take a voyage through the complex terrain of handling missing data, a critical part of data pre-processing that requires accuracy and imagination. We’ll learn about the causes and types of missingness, as well as missing value treatment.

Common Causes of Missing Values in Data Analysis

Missing data impacts all data-related professions and can lead to a number of challenges such as lower performance, data processing difficulties, and biassed conclusions as a result of discrepancies between complete and missing information. Some of the probable causes of missing data are:

Human errors during data collection and entry
Equipment or software malfunctions causing machine errors;
Participant drop-outs from the study
Respondents refusing to answer certain questions
Study duration and nature
Data transmission and conversion
Integrating unrelated datasets

Frequent missingness has the ability to reduce overall statistical power and introduce biases into estimates. The relevance of missing values is determined by the magnitude of the missing data, its pattern, and the process that caused it. Therefore, a strategy is always necessary when dealing with missing data, as poor management might produce significantly biassed study results and lead to inaccurate conclusions.

Various Types of Missing Values in Data Analysis and the Impacts

MCAR or Missing Completely at Random

In MCAR, missingness has no relationship with either observed or unobserved values in the dataset. Simply put, the lack of data occurs at random, with no clear pattern.

A classic example of MCAR occurs when a survey participant inadvertently misses a question. The chance of data being absent is independent of any other information in the dataset. This approach is regarded the best for data analysis since it introduces no bias.

MAR or Missing at Random

In MAR, the missingness may be explained by some of the observable dataset properties. Although the data is missing systematically, it is still deemed random since the missingness has no relationship to the unobserved values.

For example, in tobacco research, younger individuals may report their values less frequently (independent of their smoking status), resulting in systematic missingness due to age.

MNAR: Missing Not at Random

MNAR happens when the missingness is linked to the unobserved data. In this situation, the missing data is not random but rather linked to particular reasons or patterns.

Referring to the tobacco research example, individuals who smoke the most may purposefully conceal their smoking habits, resulting in systemic missingness due to missing data.

Treatment of Missing Values: Approach for Handling

Three commonly utilised approaches to address missing data include:

Deletion method
Imputation method
Model-based method

All these methods can be further categorised.

Furthermore, choosing the right treatment will depend on several factors:

Type of missing data: MCAR, MAR, or MNAR
Missing value proportion
Data type and distribution
Analytical objectives and assumptions

Implications/Impacts Various Missing Data

MCAR:

MCAR data can be handled efficiently with the help of simple methods such as listwise deletion or mean imputation, without compromising the integrity of the analysis;
Statistical results originating from MCAR data are usually unbiased and reliable.

MAR:

MAR data requires more intricate handling techniques such as multiple imputation or maximum likelihood estimation;
Failing to account for MAR in a proper manner may introduce biases and affect the validity of statistical analyses.

MNAR:

MNAR data is the most difficult one to handle, as the reasons for missingness are not captured within the observed data;
Traditional imputation methods may not be applicable for MNAR data, and specialised techniques are required that would consider the reasons for missingness.

Final Words

Understanding the factors that cause missing data is critical for any data scientist or analyst. Each mechanism – MCAR, MAR, and MNAR – has particular challenges and consequences for data processing.

As data scientists, it is critical to determine the proper process and apply appropriate imputation or handling procedures. Failure to treat missing data appropriately can jeopardise the integrity of analysis and lead to incorrect results. Missing data’s influence can be reduced by using proper strategies.
