Question

Find the mean and median of each data set.

Raul recorded the following golf scores in his last 7 games.
84, 94, 93, 89, 94, 81, 90

Answer 1

Mean: 89.29

Median: 90

Explanation:

Mean: the average of the set

To find the mean, add the numbers and divide by 7

(84+94+93+89+94+81+90)/ 7

= 89.29

Median: the middle number.

Arrange the numbers from least to greatest first.

81,84,89,90,93,94,94

Now start from both ends and cross them out until you get to the one in the middle.

84,89,90,93,94

89,90,93

90
