Answer:
first quartile of this data set is 13
Step-by-step explanation:
11, 12, 13, 15, 17, 19, 22, 24, 29, 33, 38
First we find the median for the given set of numbers
Median is the middle number
11, 12, 13, 15, 17, 19, 22, 24, 29, 33, 38
19 is the median of the set of numbers
First quartile is the median of the set of numbers below 19
third quartile is the median of the set of number above 19
11, 12, 13, 15, 17
Median of 11, 12, 13, 15, 17 is 13
So first quartile of this data set is 13
