Answer:
60th percentile = 23.5
Explanation:
Put numbers in order from lowest to highest:
14, 14, 14, 15, 15, 15, 16, 18, 19, 21, 23, 23, 24, 24, 25, 25, 25, 26, 29, 29
Formula:
60th percentile = 60% x Total number of elements
We have 20 scores,
60th percentile = 60% x 20
= 0.60 x 20
= 12
the 60th percentile is the 12th number on the list
14, 14, 14, 15, 15, 15, 16, 18, 19, 21, 23, 23, 24, 24, 25, 25, 25, 26, 29, 29
The 60th percentile is between 23 and 24
23 + 24 / 2 = 23.5
