Answer 1

Yours: mean: 17; median: 17; mode: none

Friends: mean: 16.4; median: 17; mode: 20

You have the higher mean.

Explanation:

a.

Your mean:

(18 + 16 + 19 + 15 + 17) / 5

= 17

Your median:

15 , 16, 17, 18, 19

= 17

Your mode:

15 , 16, 17, 18, 19

= No mode (no number comes up repeatly)

Your friend's mean:

(20 + 20 + 13 + 12 + 17) / 5

= 16.4

Your friend's median:

12, 13, 17, 20, 20

= 17

Your friend's mode:

12, 13, 17, 20, 20

= 20

b. Comparing your means, you have the higher mean
