To find the location of the pth percentile in a dataset, we need
to do the following steps:
- Multiply the total number of values in the data set by the
percentile, which will give you the index.
- Order all of the values in the data set in ascending order
(least to greatest).
- If the index is a whole number, count the values in the data
set from least to greatest until you reach the index, then take the
index and the next greatest number and find the average.
- If the index is not a whole number, round the number up, then
count the values in the data set from least to greatest, until you
reach the index.
