The Different Types of Big Data Analytics

Let us learn about the different types of big data analytics as well as check out some of their applications and real-world examples. We will also explore some of the key types of data analysis techniques used for working with big data. These analysis techniques are various applications of data science types that are used in carrying out advanced analytics on big data.

Understanding the Past: Descriptive Analytics

Descriptive analytics forms the foundation of big data exploration. Its primary focus is summarising historical data to gain insights into past events and identify trends. Think of it as painting a clear picture of what has already transpired. Descriptive analytics relies on a variety of techniques to achieve this:

• Measures of Central Tendency: These metrics, like mean (average), median (middle value), and mode (most frequent value), provide a snapshot of the typical values within a dataset. For instance, a retail company might use the average sales figures over the past year to understand their baseline performance.
• Measures of Dispersion: Variance and standard deviation quantify the spread of data points around the central tendency. This helps identify outliers and assess the consistency of data. For example, analysing the standard deviation of daily website traffic allows an e-commerce platform to understand how much traffic fluctuates throughout the week.
• Data Visualisation: Charts and graphs bring data to life, making it easier to identify patterns and trends. Descriptive analytics utilises various visualisations like bar charts, pie charts, and line graphs to showcase key insights from the data. A social media company might use bar charts to visualise user engagement metrics like likes and shares across different social media platforms.

Real-World Example: Optimising Inventory Management with Descriptive Analytics

Take a large retail chain struggling with inventory management as an example. Using descriptive analytics, they can analyse historical sales data to identify peak sales seasons and products with higher demand. By calculating average sales figures and analysing seasonal trends, they can predict future demand and optimise inventory levels accordingly. This reduces the risk of stockouts during peak seasons and prevents excess inventory holding costs during slow periods.

Diagnosing the Root Cause: Diagnostic Analytics

While descriptive analytics paints a picture of the past, diagnostic analytics delves deeper, asking "why" things happened the way they did. This approach helps identify the root causes of problems or phenomena observed in the data.

Here are key techniques used in diagnostic analytics:

• Data Mining: This process uncovers hidden patterns and relationships within large datasets. Advanced algorithms sift through vast amounts of data to identify previously unknown correlations that might explain specific trends or issues. For example, a manufacturing company experiencing a rise in product defects could use data mining to identify correlations between specific machine operators, production times, or raw material batches and the occurrence of defects.
• Drill-Down Analysis: This technique involves progressively zooming in on specific data points or segments within a larger dataset. This allows for a more granular exploration of potential causes behind observed trends. Let us take a hospital analysing patient readmission rates as an example. Through accurate types of data analysis such as drill-down analysis, they can identify specific diagnoses or patient demographics with higher readmission rates, allowing them to investigate the underlying reasons.
• Anomaly Detection: This technique focuses on identifying data points that deviate significantly from the expected pattern. These anomalies can signal potential problems or areas requiring further investigation. For instance, a financial institution might use anomaly detection to identify unusual customer transactions that could be indicative of fraudulent activity.

Real-World Example: Predicting Machine Failures with Diagnostic Analytics

A manufacturing company experiencing frequent machine breakdowns can leverage diagnostic analytics to identify root causes and predict potential failures. By analysing sensor data from the machines, such as temperature readings and vibration patterns, data mining algorithms can uncover correlations between specific data points and machine failures. This allows for preventive maintenance scheduling, preventing costly downtime and ensuring smooth production operations.

Predicting the Future: Predictive Analytics

Moving beyond the past and present, predictive analytics takes centre stage. This powerful approach leverages historical data and statistical models to forecast future trends and events. Think of it as using the past to predict what is likely to happen next.

Here are some key techniques used in predictive analytics:

• Regression Analysis: This technique establishes a mathematical relationship between dependent variables (what we want to predict) and one or multiple independent variables (factors that influence the dependent variables). For instance, a marketing team might use regression analysis to predict future sales based on historical data points like advertising spend and product pricing.
• Time Series Forecasting: This technique analyses data collected over time to predict future values in a time series. It's particularly useful for forecasting trends in areas like website traffic, stock prices, or customer demand. Think of an e-commerce platform using time series forecasting to predict upcoming sales peaks based on historical seasonal trends.
• Machine Learning Algorithms: These algorithms learn from existing data patterns to make predictions on new data. They are particularly powerful for complex data sets and can identify non-linear relationships that might be missed by traditional statistical methods. For example, a travel company might use machine learning algorithms to predict customer travel preferences and personalise travel recommendations based on past booking behaviour and demographic data.

Real-World Example: Assessing Creditworthiness with Predictive Analytics

Financial institutions rely heavily on predictive analytics to assess customer creditworthiness and identify potential loan defaults. By analysing a borrower's credit history, income data, and other financial information, machine learning algorithms can predict the likelihood of a customer repaying a loan. This allows banks to make informed lending decisions and minimise the risk of bad debt.

Optimising Decisions: Prescriptive Analytics

Predictive analytics tells you what might happen, but prescriptive analytics goes a step further. This approach leverages data and potential future scenarios to suggest optimal courses of action. Think of it as using data-driven insights to determine the best way to move forward.

Here are some key techniques used in prescriptive analytics:

• Optimisation Algorithms: These algorithms identify the best solution within a defined set of constraints. They can be used to optimise logistics routes, resource allocation, or pricing strategies based on various factors and potential outcomes. For instance, a delivery company might use optimisation algorithms to find the most efficient delivery routes for drivers, considering factors like traffic patterns and delivery locations.
• Simulation Modeling: This technique involves creating a digital model of a real-world system. By simulating different scenarios and their potential outcomes, businesses can make informed decisions about resource allocation, marketing strategies, or product development. A pharmaceutical company using simulation modelling to test the potential effectiveness of a new drug before investing in large-scale clinical trials would be an example.
• Decision Trees: These are flowchart-like structures that represent a sequence of decision-making steps. Decision trees can be used to model complex decision-making processes and identify the optimal course of action based on different conditions. For instance, a retail company might use decision trees to personalise product recommendations for customers based on their past purchase history and browsing behaviour.

Real-World Example: Optimising Delivery Routes with Prescriptive Analytics

A transportation company struggling with inefficient delivery routes can leverage prescriptive analytics to optimise operations. By considering factors like traffic patterns, delivery locations, and driver availability, optimisation algorithms can suggest the most efficient routes for each delivery. This reduces delivery times, minimises fuel costs, and improves overall customer satisfaction.

Analysing in Real-Time: Real-Time Analytics

The world of big data is not static, information is constantly being generated. Real-time analytics allows businesses to analyse data streams as they are produced, enabling immediate insights and actions. Think of it as having a live feed of insights that can be used to react to situations in real time.

Here are some key techniques used in real-time analytics:
