Find the median, mode, and range for 9.8 7.2 6.3 5.8 9.4 5.1 6.2 7.2

Median is 6.75

Mode is 7.2

Range is 4.7

Step-by-step explanation:

Given the set of data

9.8 7.2 6.3 5.8 9.4 5.1 6.2 7.2

First, we rearrange the data in an ascending or descending order.

Rearranging in an ascending order, that is from the smallest to the biggest number, we have:

5.1, 5.8, 6.2, 6.3, 7.2, 7.2, 9.4, 9.8

- The median is the middle number (If there is an odd number of data), or the average of the two middle number (If we have an even number of data).

In this case there are 8 numbers (even), and 6.3 and 7.2 are the middle numbers, so the median is

M = (6.3 + 7.2) / 2

= 13.5/2

= 6.75

- The mode is the number that occurs the most times, 7.2 occurs twice, which is more times than any other number, so the mode is 7.2

- Range is the absolute difference between the biggest and the smallest number.

Range = 9.8 - 5.1

= 4.7
