Summary

Cats Don't Like Christmas!: A Hilarious Holiday Children's Book for Kids Ages 3-7 sits at the 43th z-normalized percentile across 5,285ranked books. The z-percentile differs from a raw star average because Rankquant subtracts each reviewer's personal baseline before aggregating — so a reader who rates everything 5 stars carries less weight than one who rates discerningly. Raw-average percentile is 30; the gap between the two measures how much bias-correction changes this title's standing. How percentiles are computed.
