Question

in a statistics class, the following 10 scores were randomly selected: 74, 73, 77, 77, 71, 68, 65, 77, 67, 66. what is the median? (practice using excel with commands given in class)

Answer 1

median = 72

Explanation:

the median is the middle value of a data set , arranged in ascending order ( smallest to largest.

If there is no exact middle value then it is the average of the values on either side of the middle.

arrange data in ascending order.

65 , 66 , 67 , 68 , 71 , 73 , 74 , 77 , 77 , 77

↑ middle between 71 and 73

median = (71 + 73) ÷ 2 = 142 ÷ 2 = 72
