 Description  
 Mode:  The number that occurs most frequently in a set of numbers.

We are given these scores of two classes on a mathematics test:

Class 1: 49, 54, 55, 65, 76, 76, 76, 78, 78, 81, 83, 85, 88, 89, 89, 90, 90, 91, 93, 99

Class 2: 55, 59, 60, 65, 68, 76, 77, 77, 78, 80, 80, 80, 89, 89, 90, 92, 92, 95, 96, 98

For Class 1, 76 is the mode (it occurs 3 times). For Class 2, 80 is the mode (it occurs 3 times). Based only on the mode, it seems that Class 2 performed better than Class 1 on the mathematics test.

Do you think the mode is affected by extreme scores like the mean is?
