Now let us start analyzing more on conquering the cornerstone of data analytics in other words “the pillars of data analytics”

There are four key approaches to analyzing data:

  1. Descriptive: This focuses on understanding historical data to see what has happened in the past.

  2. Diagnostic: This seeks to identify the reasons behind certain events or trends.

  3. Predictive: This involves forecasting future outcomes based on existing data patterns.

  4. Prescriptive: This provides recommendations on actions to take based on the analysis.

1) Descriptive Analysis

Descriptive Analysis involves summarizing historical data to understand past events and trends. It answers questions about what has happened, often using metrics and visualizations to present the information.

Key Components of Descriptive Analysis:

  1. Data Collection: Gathering relevant data from various sources, such as sales records, customer feedback, website analytics, and financial statements.

  2. Metrics and KPIs: Identifying key performance indicators (KPIs) to measure success. Common metrics include total sales, customer acquisition costs, and churn rates.

  3. Summarization Techniques:

    • Averages: Calculating mean, median, and mode to understand typical values.

    • Totals: Aggregating data to provide overall figures, such as total revenue or total units sold.

    • Percentages: Understanding proportions, such as the percentage of total sales coming from a specific product category.

  4. Visualizations: Using charts, graphs, and dashboards to present data clearly and intuitively. Common visualizations include:

    • Bar Charts: For comparing different categories.

    • Line Graphs: To show trends over time.

    • Pie Charts: To illustrate parts of a whole.

  5. Data Segmentation: Breaking down data into specific groups or segments to gain deeper insights, such as analyzing sales by region, product type, or customer demographic.

Example:

Imagine an online retail company that wants to analyze its sales performance over the last year. Using descriptive analysis, the company might look at:

  • Sales Revenue: Total sales for each month to see seasonal trends.

  • Customer Demographics: Breakdown of sales by age, gender, and location to understand who their customers are.

  • Product Performance: Identifying which products sold the most and least, helping to highlight popular items.

For instance, the analysis might reveal that sales peaked during the holiday season and that younger customers are more likely to purchase tech gadgets. This information helps the company understand past performance and informs future strategies.

Benefits of Descriptive Analysis:

  • Informed Decision-Making: By understanding past performance, businesses can make better strategic choices.

  • Identifying Opportunities: Highlighting successful products or trends can guide marketing efforts and inventory management.

  • Benchmarking: Establishing a baseline for future performance comparisons.


In summary, descriptive analysis is essential for understanding what has happened in a business or market, providing the groundwork for further analysis and strategic planning.


2) Diagnostic Analysis

Diagnostic Analysis focuses on understanding the reasons behind past events or trends. It goes a step further than descriptive analysis by not only summarizing what happened but also investigating why it occurred. This type of analysis is crucial for identifying patterns, correlations, and causative factors that can inform future decision-making.

Key Components of Diagnostic Analysis:

  1. Data Exploration: Analyzing historical data to identify anomalies, trends, and patterns that require further investigation.

  2. Correlation Analysis: Assessing relationships between different variables to determine if and how they impact each other.

  3. Root Cause Analysis: Identifying the underlying factors that contribute to specific outcomes or issues. Techniques may include the "5 Whys" method or fishbone diagrams.

  4. Comparative Analysis: Comparing different time periods, regions, or customer segments to uncover insights.

  5. Statistical Techniques: Using statistical methods to analyze data, such as regression analysis, to quantify relationships between variables.

Example:

Imagine a hotel chain that experiences a sudden drop in customer bookings during a specific month. The management wants to understand why this happened.

  • Data Exploration: The hotel examines booking data from previous months and compares it to the month in question. They notice a significant decline in bookings in one specific location.

  • Correlation Analysis: The team investigates if there were any external factors, such as a local event or seasonality. They find that a major festival that usually boosts bookings was canceled that month.

  • Root Cause Analysis: To root around in deeper, the hotel looks into customer reviews and feedback. They discover that recent renovations created noise and discomfort, causing negative experiences for guests.

  • Comparative Analysis: They compare the affected hotel’s performance to other locations that didn’t experience the same issues, confirming that the problem was localized.

Benefits of Diagnostic Analysis:

  • Informed Problem-Solving: Understanding the reasons behind issues helps businesses address them effectively.

  • Targeted Improvements: Identifying specific causes allows for targeted interventions, such as adjusting marketing strategies or improving customer service.

  • Preventive Measures: By understanding past problems, businesses can implement measures to avoid similar issues in the future.

In summary, diagnostic analysis is essential for uncovering the "why" behind past events, enabling organizations to learn from their experiences and make data-driven improvements.


3) Predictive Analysis

Predictive Analysis involves using historical data, statistical algorithms, and machine learning techniques to forecast future outcomes. It aims to identify patterns and trends that can help organizations anticipate what might happen next, allowing for proactive decision-making.

Key Components of Predictive Analysis:

  1. Data Collection: Gathering relevant historical data from various sources to serve as the foundation for predictions.

  2. Model Development: Creating statistical or machine learning models that can analyze the data and identify patterns. Common techniques include regression analysis, decision trees, and neural networks.

  3. Validation: Testing the accuracy of the predictive models using a separate dataset to ensure they can reliably forecast outcomes.

  4. Forecasting: Using the validated models to predict future events or behaviors based on the insights derived from historical data.

  5. Monitoring and Updating: Continuously monitoring the performance and updating it with new data to improve accuracy over time.

Example:

Consider an e-commerce company that wants to predict customer purchasing behavior to optimize inventory management.

  • Data Collection: The company collects historical data on customer purchases, browsing behavior, seasonal trends, and marketing campaigns.

  • Model Development: Using techniques like regression analysis, the company develops a model to predict which products customers are prone to purchase in the next quarter.

  • Validation: The model is tested against historical data from previous quarters to evaluate its accuracy.

  • Forecasting: The predictive model indicates that certain products are likely to see a spike in demand during an upcoming holiday season, based on past purchasing trends.

  • Monitoring and Updating: After the holiday season, the company assesses the model's performance and incorporates any new data, refining the model for future predictions.

Benefits of Predictive Analysis:

  • Proactive Decision-Making: Organizations can anticipate future trends and adjust strategies accordingly, reducing risks.

  • Optimized Resources: By predicting demand, businesses can optimize inventory levels, reducing costs associated with overstocking or stockouts.
