Question

what is the difference in the median and the mode in the data set 20, 19, 22, 15, and 20?
20
15
5
0

Explanation:

Step1: Arrange data in ascending order

$15, 19, 20, 20, 22$

Step2: Find the median

Since there are 5 data - points (an odd number), the median is the middle value. So, the median is 20.

Step3: Find the mode

The mode is the number that appears most frequently. Here, 20 appears twice and other numbers appear once, so the mode is 20.

Step4: Calculate the difference

Median - Mode = $20 - 20=0$
