64 + 77 + 79 + 80 + 84 + 86 + 90 + 90 + 94 + 96 + 97 + 98 =1035
1035 divided by 12 = 86.25
Compare two means
Team 1: 72 + 73 + 76 + 76 + 78 = 375
375 divided by 5 = 75 inches
Team 2: 67 + 72 + 76 + 76 + 84 = 375
375 divided by 5 = 75 inches
The two teams have the same mean!
Outlier affects the mean
Mean with the outliers: 35
Mean without the outliers: 25
With the outlier, the mean is a lot higher than without the outlier.
The mean is best represented without the outlier.
