Percentile Analyzer

What it does

The Percentile Analyzer skill calculates the percentile rank of a given value within a dataset. It can process lists of numbers and determine where a specific data point falls relative to others, providing insights into distribution and performance. This allows for comparisons beyond simple averages or medians.
