CompTIA Data+ DA0-002 (V2) Practice Question

A retail analyst is preparing a customer-level table for a marketing dashboard. The numeric field lifetime_value ranges from 4 USD to 18 960 USD and is heavily skewed. The marketing team wants the dashboard to display five segments (very-low, low, medium, high, very-high) so that roughly 20 % of customers fall into each segment. Which data-transformation technique will most efficiently create the required five equally populated groups?

  • One-hot encoding of the lifetime_value column

  • Equal-frequency (quantile) binning

  • k-means clustering with k = 5

  • Rescaling the field with min-max normalization
