Find the values of the 30th and 90th percentiles of the data
18, 9, 7, 5, 11, 7, 17, 20, 19, 2, 17, 12, 5, 1, 13, 12, 11, 15, 16, 20
* 30th percentile = 9
90th percentile = 20
* 30th percentile = 9
90th percentile = 19
* 30th percentile = 11
90th percentile = 19
* 30th percentile = 7
90th percentile = 20

Arrange scores in order of value. With 20 scores, each stands for 5% of the distribution. 30th percentile involves the six lowest scores. Can you generalize that for the 90 percentile?
