# Percentile Rank Calculator

Instructions: This percentile rank calculator will calculate a percentile rank associated to a $$X$$ value specified by you, for a sample data set provided by you in the form below. Please type in the dataset and the required value of $$X$$ for which you want to compute the percentile rank:

Type the sample (comma or space separated)
Value (X) =
Name of the variable (Optional) =

The idea of computing a percentile rank associated to a given value $$X$$ consists of finding the percentage of values in the dataset that are less than $$X$$. Indeed, let $$k$$ be the number of values in the dataset that are less $$X$$, and let $$n$$ be the sample size. The associated percentile rank is computed as:

$P = \frac{ k}{n}$
