25+29= 54
54/2
27
Q1= 27

The first quartile of the data 33, 25, 42, 25, 31, 37, 46,29,38 is 27.

How to find the first quartile?

The first quartile of the data can be found as follows:

Firstly, let's arrange the data in ascending order.

25, 25, 29, 31, 33, 37, 38, 42, 46

Therefore,

Median is the middle number = 33

25, 25, 29, 31

first quartile = 25 + 29 / 2
