Answer:
a) Mean (the average): 4
Median: 4
Mode: 4
b) Outlier: 10
Step-by-step explanation:
a) Mean: 0+2+2+9+28+10+12+7+10 = 80
80/20 = 4
Median: 0, 1, 1, 2, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 5, 5, 6, 6, 7, 10
(the middle: 4)
Mode: the most shown-up number: 4
b) Outlier: the odd one out
10, because all of the numbers have a difference of increasing by one except for the 10 on the far edge.
