04. Comparison

Definition

When your problem statement requires the comparison of two data features or cohorts

_ Example_

Problem statement reads: What are the demographic differences between the Top 10% of FIFA players by market value and the remaining 90% of players?

Which visualization will work best?

1. Box plots will provide a comprehensive picture of how the two cohorts are comparing:

• Center will tell if on average the cohorts are similar
• Spread will tell you if they vary differently
• Shape (symmetry, skewness) will indicate any asymmetry
• Unusual features (outliers, missingness)
