Category: Analytics

When conducting research, categorical data is of the utmost importance. Research involves the application of two types of data — categorical data and numerical data. Categorical data refers to a kind of qualitative data that may be classified into several categories. The data comprises categorical variables that can only be expressed in natural language. While numerals may be used to represent categorical data, there is no mathematical aspect of categorical data. 

Categorical data generally includes data on birth, hair colour, body weight, height, and other factors relevant to any specific research. A deep understanding of categorical data is crucial to conducting data analysis in research. 

If you seek to delve deeper into categorical data, then you may consider pursuing a career in data science. Enrol in a data science certification course to gain a deep insight into the nuanced aspects of categorical data for data analytics. Read on to learn more about categorical data to become a data analyst and conduct in-depth data analysis in your research.

Categorical Data: Types

Categorical data primarily includes points of observation and values that can be grouped into definite classes based on characteristics. Specifically, categorical data is of two types: nominal and ordinal.

Nominal data is a type of categorical data that cannot be ranked hierarchically. While nominal data can be both quantitative and qualitative at times, yet, it cannot be measured or arranged in a ranked order. Symbols, letters, and words are some instances of nominal data. Ordinal data is the type of categorical data that possesses a natural order. Ordinal data is generally used in surveys and questionnaires.

A deeper understanding of nominal and ordinal data can be acquired by pursuing a Data analytics certification course.

Primary Characteristics of Categorical Data

The key features of categorical data are listed below:

• Just as the name suggests, categorical data can be classified into groups. Based on the nature of the data, categorical data can be grouped into non-binary and binary categories.
• The classes into which categorical data is classified are created based on qualitative characteristics
• Categorical data can constitute numerical values that do not have a mathematical aspect.
• Categorical data can be represented in the form of bar charts and pie charts.
• Data science recommends using median and mode functions for analysing categorical data. While the mode function is used for nominal data analysis, both median and mode functions are used for ordinal data analysis.

If you seek to better understand the characteristics of categorical data in data analytics, you may consider enrolling in data science training courses.

Ways to Analyse Categorical Data in Data Analytics

Analysing categorical data may be a bit complex, which is why you may need to enrol in a data analytics course to learn the fundamentals of data analysis. The procedures for analysing categorical data are briefly described below:

Tabulation

The tabulation procedure is for summarising a column of variable data. This procedure is for tabulating the incidence of occurrence of every distinct value in the column. Each incidence is then represented in tabular and graphical forms.

Frequency tables

This procedure is for analysing singular and tabulated categorical factors. The frequency of occurrence of the singular categorical factor is represented in the form of a pie chart or a bar chart. Data analysts also conduct statistical tests to ensure that the singular categorical factor is aligned with multinomial probabilities.

Contingency tables

This procedure is for the analysis and display of frequency data tabulated in two-way tables. Data analysts apply statistical analysis techniques to quantify the degree of relationship between the columns and rows of the contingency tables.

Correspondence analysis

This analysis involves the creation of a map of columns and rows in a 2-way contingency table. The map provides insight into the degree of association among the categories of column and row variables.

Multiple correspondence analysis

This procedure involves the creation of a map denoting the relationships among the categories of at least two variables. The map also discloses interrelationships among the data variables.

Crosstabulation

This procedure is for the summarisation of two columns of variable data. Analysts construct a two-way table to indicate the incidence of occurrence of every unique pair of attributes in the columns. In this procedure, the degree of association among the columns is quantified, and statistical tests are conducted to determine the degree of dependence between the value in one column and the value in the other column.

Item reliability analysis

This procedure refers to the analysis of categorical data in a way to estimate the consistency of a group of attributes. The output of item reliability analysis is graphically represented in a Cronbach’s alpha plot.

There are several other procedures for analysing categorical data in data analytics. To understand the statistical procedures of categorical data analysis, you may sign up for a data analytics course and consider a career in data analytics.

Examples of categorical data

The example herein may make understanding the basics of categorical data easier. Let’s say that you are throwing a party and want to serve your guests welcome drinks. So, you make a quick survey and jot down the data in a table, as given below:

Drinks	Frequency
Mirinda	04
Coke	02
Sprite	06
Fanta	01

The data in the table is categorical, as evident from how the data has been grouped into distinct classes.

Conclusion

Determining between categorical and numerical data is crucial for data analysis. While categorical data possesses distinct labels or categories, numerical data comprises quantifiable variables. It is also important to be well aware of the procedures of analysing categorical data to conduct and conclude a successful research work. To be an expert in the fundamental and advanced concepts of categorical data, you may sign up for the Postgraduate Program In Data Science And Analytics, the data science course offered at Imarticus.

Probability is a mathematical concept that predicts the likelihood of an event occurring. Understanding the probability theory and probability distribution is important for performing data analysis. This blog will discuss the concepts of probability theory and distribution in detail. 

If you want to build a career in data analytics, enrolling in a credible data science course can help you gain the hands-on experience needed. 

What is probability theory?

Probability theory is a branch of mathematics that studies the properties and behaviour of random phenomena, such as outcomes, events, distributions, and variables. Probability theory offers a framework for quantifying the likelihood of various scenarios, analysing the uncertainty and variability of data, and testing assumptions and hypotheses. 

Importance of probability theory in data analysis 

Data is generally noisy, incomplete, or subject to errors and biases, making it difficult to draw reliable and accurate conclusions from it. Probability theory is necessary for data analysis as it helps in dealing with inherent variability and uncertainty of data. 

With probability theory, it is easier to account for the sources of variability and uncertainty and to express confidence and certainty in the results. This theory also allows us to compare the different methods, models, and strategies for data analysis and for evaluating their validity and performance. 

Terms used in probability theory 

In order to understand the application of probability theory, there are some terms that you must be familiar with. These are as follows: 

Random experiment 

A random experiment can be defined as a trial that is repeated several times to get a well-defined set of possible outcomes. For example, tossing a coin. 

Sample space 

It can be defined as the set of all possible outcomes that result from conducting a random experiment. For instance, the sample space of tossing a coin is (tails, head). 

Event 

It can be defined as a set of outcomes of any particular experiment which forms a subset of the sample space. The different types of events are as follows: 

• Independent events: The events which are not affected by any other events are called independent events. 

• Dependent events: The events which are affected by other events are called independent events. 

• Mutually exclusive events: The events which cannot take place at the same time are called mutually exclusive events. 

• Equally likely events: Two or more events that have the same chance of taking place are called equally likely events. 

• Exhaustive events: The event which is equal to the sample space of an experiment is called an exhaustive event. 

Random variable 

A random variable, in probability theory, is a variable that considers the value of all possible results of an experiment. There are two kinds of random variables: 

• Discrete random variable: These variables can be counted to an exact value like 0,1,2,…and so on. 
• Continuous random variable: These variables can have an infinite number of values called the continuous random variable. 

If you want to learn about probability theory in detail, enrolling in a credible data science course can be very helpful. 

What are probability distributions? 

It is a statistical function that defines all the possible values and probabilities of a random variable within a given range. This range is going to be bound by the minimum and maximum possible values. However, the possible values which are to be plotted on the probability distribution are going to be decided by several factors. Some of these factors are skewness, standard deviation, kurtosis, and average.

Types of probability distributions 

There are two kinds of probability distributions: 

1. Discrete probability distributions 
2. Continuous probability distributions 

Discrete probability distribution 

This is a distribution where the observations can take only a finite number of values. For instance, the rolling of a dice can have only one number ranging from 1 to 6. There are several types of discrete distributions such as: 

Bernoulli distribution 

In this type of distribution, only one experiment is conducted which results in a single observation. Hence, this type of distribution describes events that can have exactly two outcomes. For example, flipping a coin can have only one of the two outcomes – heads or tails. 

Binomial distribution 

In this type of distribution, there can be a finite number of possibilities. It is like an extended version of Bernoulli’s distribution. Repeating the Bernoulli trials, n number of times, we will get a binomial distribution. 

Poisson distribution 

This is a type of distribution used in statistics to show how many times an event is likely to occur over a given period. Poisson distributions are generally used for comprehending independent events at a constant rate during defined time intervals. 

If you want to know more about these distributions, join a data analytics course that will help you understand the real-world implications of these distributions. 

Continuous probability distributions 

This type of distribution can define the probabilities of the possible values of a continuous random variable. Continuous distributions have smooth curves, unlike discrete distributions, which have an infinite number of samples.

Normal distribution 

Also known as the Gaussian distribution, this is the most common and naturally occurring distribution. This distribution is seen in almost every field – statistics, finance, chemistry, etc. This probability distribution is symmetrical around its mean (average) value. It also signifies that the data close to the mean occurs more frequently than the data that is far from it. 

Exponential distribution 

An exponential distribution, in a Poisson process, is a continuous probability distribution that describes the time period between the events occurring. 

Continuous uniform distribution 

In this type of distribution, all the outcomes are equally possible. Every variable has the chance of occurring as a result. In this symmetric distribution, the variables are spaced evenly, having a 1/(b-a) probability. 

Log-normal distribution 

This is a continuous distribution of random variables, whereas the natural logarithms of these random variables are a normal distribution. A log-normal distribution is always going to yield a positive value as opposed to a normal distribution. 

Conclusion 

Probability is an estimation of how likely an event or outcome can occur. Probability theory serves as the backbone of a number of data science concepts. Probability theory deals with the uncertainty associated with data. 

The probability distribution is the set of all the possible outcomes of any random event or experiment. It has many real-life applications in areas such as engineering, business, medicine, and many more industries. It is used mainly to make future predictions based on a sample for a random event.

In today’s data-driven world, piloting a flourishing company requires gathering proper data that can be read, analysed and reported to gain in-depth insights into market conditions and consumer behaviour. Data has been used for years by many of the biggest MNCs in the world such as Google, Amazon, Netflix etc which has clearly shown their success in the business world. However, developments in the discipline of data mining and data cleaning have shown the importance of data for performing various organisational tasks.

Preparing the right data that can be analysed and based on which essential business is taken is a critical job. An effective data science course can help professionals learn and evaluate which data is important and how to proceed with raw data so that valuable and readable conclusions can be derived. 

Read on to learn about the importance and process of cleaning, mining and preparation of data that is utilised for performing crucial organisational tasks and activities.

What is Data Cleaning?

Data cleaning is the practice of restoring, rectifying and eliminating inaccurate, tainted, improperly formatted, replicated, or incomplete data from a particular dataset. At the time of integrating various datasets, data often gets mislabelled or replicated which stays in the form of duplicate data. However, even if the data appears to be correct in terms of algorithm, it becomes unreliable if the data is incomplete or inaccurate.

The process of data cleaning does not come with a manual as various types of data require to be cleaned in different ways. Hence, one concrete method can not be prescribed for every type of data. However, to be able to know that one is conducting the process of data cleaning in the right manner or not creating a template every time while carrying out the procedure is a formula that really helps. 

How Data Mining, Cleaning and Preparing Help in Performing Organisational Tasks?

For performing various organisational tasks, different departments require different types of data. However, companies do not get the data in ready-to-use format. It is the data analytics and data science professionals who convert the raw data, perform data mining, and data cleaning and prepare the data in such a manner that can be used for performing market research and other tasks. 

Professionals can take up an insightful data analytics course to understand how to track valuable data and prepare it for further organisational tasks. Here is how data mining and cleaning helps to perform various organisational tasks: 

Boosts revenue

The first and foremost benefit of preparing data properly is that it reduces the redundancy of efforts within an organisation. Companies that significantly perform data mining and cleaning processes can see a noticeable change in their revenue because of the increase in accuracy and consistency of data. 

Hence, the response rate increases and redundancy of work reduces which in turn reflects a positive growth in the company and a boost in revenue can be seen. Also, better interaction within the organisation and with the consumers can help companies make better decisions. Clean and prepared data allows marketers to locate prospects of high value, conveniently. With the help of clean data, it becomes easier for marketers to target specific individuals with tailored communication that is capable of generating high-value business results.

Complies reliable information

Data cleaning and mining is one of the best ways in which companies can extract reliable information. Businesses can carry out their organisational tasks in a more accurate and precise manner if they know that the information they have is concrete and reliable.

To perform organisational tasks accurately, professionals require reliable data sources. Data analytics and data science professionals work with that data and convert it in a manner that is readable and understandable by the other employees or even the general public for that matter. Hence, continuously performing data cleaning activities allows businesses to keep track of their information and vouch for its reliability.

Detects fraud

Data mining and cleaning help data science professionals quickly detect any fraud or hazardous activities so that they can take defensive actions. They can easily identify hidden patterns and initiate automated resolution techniques that are required to eliminate any sort of fraudulent activity.

Early detection of fraud helps companies to prepare better risk models and take corrective actions immediately. This continuous process allows the company to build better product safety that consumers can rely upon.

Makes informed decisions

When businesses have clean and reliable data at hand, it becomes easier for them to make data-driven decisions. Such decisions are based on real-time data and the scope of predictive analysis declines. Gathering data allows businesses to keep track of the market conditions which ultimately helps them to make more informed decisions.

Also, regular survey data on customers take some references Help companies to choose the target audience and launch products and services accordingly. An effective data analytics course assists data professionals in understanding the value of real-time data so that they can segregate between which data to consider and which data to discard.

Increases productivity

Performing data cleaning and data mining activities regularly enhances the data quality of the business and reaches a proficient level of productivity in business. As data cleaning helps to streamline the process of data analysis, it results in cost reduction and the performance of the business significantly improves.

Conducting the data cleaning and data mining process effectively allows the data scientist and data analysts to focus their energies on researching data rather than gathering it. Therefore, the ultimate productivity of the company is enhanced.

Saves company costs

As data cleaning streamlines the data-gathering process, it results in reducing company expenses which ultimately saves company costs. With the 

reduced expenditure, companies can use the budget in various other sectors and constantly strive to make better products for their target audience. 

Conclusion

In a world of fierce competition, making data-driven decisions is very important. For that, companies need to have accurate and quality data. One cannot underestimate the value of proper business research in order to gather the right sort of data. 

Using tried and tested market research techniques is the best way to collect reliable information which also ensures that the data is cleaned and prepared before using it.

Are you ready to embrace the AI-driven future?

The distinction between supervised and unsupervised learning forms the foundation for diverse applications across various sectors in machine learning. Unsupervised learning, in which algorithms discover patterns from data without labels, and supervised machine, where labelled data guides forecasting algorithms, are important approaches driving the advancement of artificial intelligence.

Knowing the unique characteristics and capacities of these approaches becomes essential as organisations and researchers use machine learning to uncover insights, make data-based choices, and innovate across industries. 

This article delves into the fundamental principles, practical uses, complexities, and decision-making methodologies essential for overseeing the realms of both supervised and unsupervised learning environments. We will delve into their strengths, limitations, and crucial distinctions, offering a comprehensive guide for practitioners seeking to adeptly leverage these approaches and, in turn, shape the trajectory of artificial intelligence development.

Supervised Learning

The supervised learning strategy in machine learning uses designated data sets to develop algorithms that accurately recognises inputs or generate outputs. The data with labels is used by the model to assess the importance of various attributes in order to gradually enhance the model fit to the predicted result.

Supervised learning has been divided into two categories:

• Classification
• Regression

Classification

Categorization or classification is implemented when the output parameter involves classifying between two or more classes, such as yes or no, correct or incorrect, and so forth.

In case of determining whether an email is spam or not, it becomes necessary to train the system on what constitutes spam. This training is accomplished by implementing spam filters, which scrutinise the email’s content and inbox for any misleading information.

All of these criteria are used to evaluate the email and provide an incorrect value to it. The lesser the email’s overall spam outcome, the less probable it is a fraud.

The algorithm determines whether a fresh email that arrives should be routed to the mailbox or the spam box according to their subject matter, categorise, and spam score.

Regression

When the outcome of a parameter is a genuine or constant value, regression is utilised. There is a connection among multiple variables, which means that an alteration in one variable is related to a modification in the other. For example, income based on previous employment or weight depending on height, etc.

Consider a glimpse at two factors: humidity and temperature. In this scenario, ‘temperature’ is the variable that is independent, and ‘humidity’ is the one that is dependent. The humidity decreases as the temperature rises.  

The algorithm provides these two variables, and the algorithm learns the link between these. After instruction, the system can easily forecast humidity relying on the provided temperature. 

Unsupervised Learning

Machine Learning techniques are used in unsupervised learning to examine and classify datasets without labels. Without human intervention, these algorithms can discover previously unseen trends in data.

Unsupervised learning is further categorised as follows:

• Clustering
• Association

Clustering

Clustering is a method of arranging components into clusters that are similar but not identical to components within distinct clusters. For example, determining whether customers purchased similar products.

Assume a telecommunications business wants to reduce customer churn by offering personalised call and internet plans. clients’ behaviour is examined, and the model groups clients with similar characteristics together. Several tactics are used to reduce turnover and maximise revenues through appropriate marketing and campaigns.

Association

The association is a rule-driven machine learning technique for determining the likelihood of elements in a collection co-occurring. For example, figuring out which items have been bought together

Assume a consumer goes to the grocery and purchases bread, milk, veggies, and grains. Another consumer arrives with bread, milk, grains, and butter. When another client walks in, it is highly probable that if he purchases bread, he will also buy dairy products. As a result, a relationship is formed based on client behaviour, and solutions are provided. 

Contrasts in Approaches: Supervised versus Unsupervised Learning

It is straightforward to grasp the variances between supervised and unsupervised learning if the fundamentals of each are known.

The major difference between the two methodologies is separating labelled and unlabeled datasets. Labelled datasets are used for developing prediction or classification algorithms in supervised learning. The labelled “training” data is put in, and the algorithm continuously modifies how it prioritises different data elements until the algorithm is properly suited to the desired result. 

Supervised machine models outperform their counterpart techniques in terms of precision. They do, however, necessitate the involvement of people in the data processing operation to guarantee that the labels on the material are suitable.

A supervised learning method, for example, can forecast flight timings based on the busiest times at an airport, air travel delays, and the climate. However, humans are required to label the datasets in order to instruct the algorithm on how these parameters affect flight durations. In order to determine that snow plays a role in flight delays, a supervised model relies on predicting the outcome.

Unsupervised learning structures, on the other hand, perpetually function without human intervention. Using unlabeled data, they discover and conclude at an order of sorts. The only human assistance required here is for outcome parameter confirmation. 

For example, if a person buys a new laptop through the internet, a system of unsupervised learning will recognise that the individual corresponds to a collection of consumers who purchase a set of identical items frequently. A data analyst’s task is to confirm that the recommendation tool presents a choice for a laptop bag and screen protection.

Summing Up

The path taken via supervised and unsupervised learning arises as a distinguishing pathway as the edges of the Artificial Intelligence program continue to advance. These approaches form the foundation of AI training programs, each providing distinctive perspectives through which machines interpret and process data.

Understanding the domains of supervised learning, in which labelled data moulds prediction models, and unsupervised learning, in which algorithms identify patterns from unlabeled data, reveals the enormous spectrum of AI possibilities. The many distinctions between these techniques, from data needs to algorithmic underpinnings, enable professionals to make informed choices about model selection and implementation.

In order to keep up with the changing trends and rapid innovations, Imarticus offers an Executive Programme In AI For Business to nurture aspirants with the highest learning experiences, turning them into exceptional AI and Machine Learning professionals.

Hadoop Distributed File System (HDFS) is the primary data storage system used by all Hadoop applications. This is an open-source, structured application. HDFS works by facilitating quick data flow between multiple nodes. It is an extremely useful framework, and companies that deal with a huge data pool frequently employ HDFS daily.

HDFS has grown to become an essential part of the Hadoop system as it supports big data and provides a way to manage large data sets. Companies are using HDFS globally as a means to store data since it offers a high degree of credibility and security.

Read on to learn the fundamentals of the Hadoop Distributed File System and its importance in building a career in data science.

What is Hadoop Distributed File System (HDFS)?

HDFS stands for Hadoop Distributed File System, and as the name suggests, it functions as a distributed file system for most of the commodity hardware. It is designed in a way that helps companies store and manage large amounts of data conveniently. HDFS is exclusively the file system of Hadoop, which offers access to data stored in the Hadoop system, making it a subset of Hadoop.

HDFS is built and developed to run on cost-effective standard hardware. It is a robust, resilient and dependable application that easily offers streaming access to data files in Hadoop Apache.

It offers easy access to data applications to the intended users, making it appropriate when dealing with big data sets. One can enroll in a data analyst course to better understand the foundation of and how it benefits businesses.

Features of Hadoop Distributed File System 

HDFS is a very useful tool for global companies, but what makes it so useful can be understood with the help of its unique features that are enumerated below:

• Data replication: This feature helps protect against data loss and ensures the availability and accessibility of data. For instance, replicated data can be retrieved from another location in a cluster in case of a mishap of node breakdown, hardware breakdown, problem in a specific application, etc.
• Reliability and fault tolerance: As HDFS can replicate data and store a cluster of the same in a variety of locations, it is a highly reliable and fault-tolerant tool. One can easily retrieve and access data from a duplicate location even if the original storage has become faulty.
• Scalability: A cluster can expand to hundreds of nodes to match escalating requirements. HDFS possesses the ability to store and keep data across multiple cluster nodes.
• High availability: HDFS offers very high data availability as it can access and retrieve data from the NameNode in circumstances where the DataNode fails to perform its prescribed functions.
• High throughput: With the help of the distributed data storage model of HDFS, data can concurrently be processed on a collection of nodes. This feature allows rapid processing and ultimately reduces processing time.
• Data locality: Instead of letting the data relocate to the location of the operational unit, HDFS allows computing and processing of the data on the DataNodes, which is the primary storage location of the data. It reduces the travel span between computation and data, which results in the reduction of network congestion. It also enhances system throughput with the help of this method.

Advantages of Hadoop Distributed File System 

Hadoop Distributed File System is an advantageous proposition for most companies. One can gain a deeper insight into the benefits of HDFS with the help of effective online and offline data analytics courses.

The following are the major benefits offered by HDFS:
