2. Diagnostic Analytics (Why did it happen?)

• Examines data to determine the causes of past outcomes.
• Helps businessesunderstand reasons behind customer churn or low-performing products.

3. Predictive Analytics (What could happen?)

• Uses statistical models and machine learning toforecast future trends.
• Essential forfinancial market predictions, demand forecasting, and fraud detection.

4. Prescriptive Analytics (What should be done?)

• Providesactionable recommendationsbased on data insights.
• Used inautomated decision-making systemssuch as dynamic pricing models and AI-driven chatbots.

The Data Analytics Process

Understanding the analytics lifecycle ensures accurate, reliable, and actionable insights.

Step 1: Data Collection

Gather structured and unstructured data from sources like CRM systems, social media, transaction logs, and IoT devices.

Step 2: Data Cleaning

Remove duplicate entries, correct inconsistencies, and fill missing values to improve data accuracy.

Step 3: Data Analysis

Use statistical methods, AI-driven models, and machine learning techniques to detect patterns, correlations, and anomalies.

Step 4: Data Visualization

Present findings through interactive dashboards, charts, and graphs for easier interpretation.

Step 5: Decision-Making & Implementation

Convert insights into strategic actions, optimizing marketing campaigns, resource allocation, or customer engagement strategies.

Detailed Example: Data Analytics in Retail

Consider a retail company analyzing one year’s worth of sales data:

1. Data Collection:Extract sales figures, customer demographics, product preferences, and seasonal trends.
2. Data Cleaning:Remove inconsistencies, missing fields, and duplicate records.
3. Data Analysis:Identifybest-selling products, peak sales periods, and customer buying behaviors.
4. Data Visualization:Use heat maps, bar charts, and trend graphs to uncover hidden patterns.
5. Decision-Making:
   • Stockhigh-demand items before peak seasons.
   • Offerpersonalized promotionsbased on past purchases.
   • Adjustpricing strategiesusing market demand forecasts.

This data-driven approach improves inventory management, reduces stock shortages, and increases revenue.
