Question

Find the median and mean of the data set below: 19 , 20 , 40 , 3 , 17 , 5 , 22

Answer 1

Median: 19

Mean: 18

Explanation:

Numbers: 19, 20, 40, 3, 17, 5, 22

Number in order from least to greatest: 3, 5, 17, 19, 20, 22, 40

The median is the number in the middle of a data set.

The median is: 19

The mean is the average of a set of data.

The mean is:
`(3 + 5 + 17 + 19 + 20 + 22 + 40)/(7)` = 18

So, Median is 19

Mean is 18
