Question

What is the first quartile of this data set?

Answer 1

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

Answer 2

The median is 19 and the lower quartile is the middle number of the 5 numbers before 19 
So its 13
