Segment Analysis
Discover natural data segments and analyze group differences: clustering-based segmentation, cross-tabulation, statistical comparison between groups, and segment profiling. Use when looking for natural groupings or comparing subpopulations.

About
Segment Analysis
Purpose
Discover natural segments in your data and characterize how groups differ. Combines unsupervised clustering with statistical comparison to reveal meaningful subpopulations.
How It Works
Step 1: Identify Segments
- Predefined segments: Analyze existing categories (e.g., by plan tier, region)
- Data-driven segments: Discover groups using K-means, DBSCAN, or hierarchical clustering
- Optimal cluster count via elbow method, silhouette score, gap statistic
Step 2: Profile Each Segment
- Size: count and percentage of total
- Demographics: distribution of key features per segment
- Behavior: mean/median of behavioral metrics per segment
- Distinguishing features: what makes each segment unique
Step 3: Compare Segments
- Statistical tests for group differences (ANOVA, Kruskal-Wallis, chi-squared)
- Effect sizes (Cohen's d, eta-squared)
- Pairwise post-hoc comparisons with multiple testing correction
Step 4: Actionable Insights
- Name each segment with a descriptive label
- Rank segments by business value or analytical interest
- Recommend targeted actions per segment
Usage Examples
"Segment our users based on engagement patterns and tell me
how each segment differs in conversion rate""Compare feature usage across free, pro, and enterprise tiers —
which features drive upgrades?"Output Format
- Segment Profiles: Descriptive summary of each segment
- Comparison Table: Side-by-side metrics with statistical significance
- Visualizations: Segment distributions, radar charts, parallel coordinates
- Python Code: Segmentation and profiling script
