In the equation, p represents the percentile and n represents the total number of items in the data set.

What is the difference between a percentile and a percentile rank?

While each percentile refers to a point, each percentile rank covers an entire interval. When we start with a given proportion or percentage, we compute a percentile whose value is some raw score; when we start with a given raw score or interval, we compute a percentile rank whose value is between

0 and 100

.

How many percent is quartile 3 if you interpret it?

Third quartile:

(above the median)

How do you find the 20th percentile?
