Purpose: Make predictions based on historical data patterns.
In summary, descriptive analytics involves organizing, summarizing, and visualizing data to uncover valuable insights. It serves as the foundational step for more advanced analytics and decision-making processes, helping businesses understand historical trends and patterns.
Diagnostic Analytics: Uncovering the “Why” Behind Trends
Diagnostic analytics is about answering the question: “Why did this happen?” It takes descriptive analysis a step further by exploring relationships between variables and identifying causal links. It helps businesses understand the reasons behind trends and movements.
Key Techniques in Diagnostic Analytics
Root Cause Analysis
Definition: Root cause analysis identifies the fundamental factors that led to an event or outcome. It digs deeper than surface-level observations to uncover the underlying causes.
Techniques: Correlation analysis, regression analysis, and dependency analysis.
Purpose: Investigating trends and patterns to uncover the root causes, improving decision-making and problem-solving.
Comparative Analysis
Definition: Comparative analysis compares different datasets or segments to identify variations and trends. It highlights differences and similarities in performance.
Purpose: Identify performance trends across various entities, such as regions, products, or time periods.
Hypothesis Testing
Definition: Hypothesis testing involves statistically validating or rejecting explanations for observed outcomes.
Process: Formulate hypotheses, collect data, and perform statistical tests (e.g., t-tests, chi-square tests) to assess relationships.
Purpose: Provide evidence for or against hypotheses and support data-driven decisions.
Drill-Down Analysis
Definition: Drill-down analysis examines data at a granular level to uncover deeper insights that may not be visible at higher levels.
Purpose: Identify trends or patterns that require deeper analysis, often using pivot tables or interactive dashboards.
Cohort Analysis
