Question

Find the mean median and mode of the data set round to the nearest tenth 15,13,9,9,71,11,10,13,1,13

Answer 1

1, 9, 9, 10, 11, 13, 13, 13, 15, 71

Median: 12

Mode: 13

Mean: 1 + 9 + 9 + 10 + 11 + 13 + 13 + 13 + 15 + 71 = 165/10 = 16.5

Answer 2

Organize: 1, 9, 9, 10, 11, 13, 13, 13, 15, 71

Mean: 16.5

Median: 12

Mode: 13

Explanation:

Mean (average): 1+9+9+10+11+13+13+13+15+71 = 165 165/10 = 16.5

10-> how many numbers

Median (middle #): 1, 9, 9, 10, 11, 13, 13, 13, 15, 71

(11+13)/2 = 12 <---11 and 13 because there are two middle numbers, so you calculate the average of those two #s

Mode (most frequent #): 1, 9, 9, 10, 11, 13, 13, 13, 15, 71 --->13 appears the most
