Given the following data set, find the value that corresponds to the 75th percentile.
10, 44, 15, 23, 14, 18, 72, 56
The 75th percentile will technically be 47 where 75% of the data (in this case 3/4th of 8 data points=6) will be below 47.
But since 47 is not one of the values, we can take it as 56, the next higher one. ...
This provides an example of finding percentile of a data set.
