A. Find the mode of the following set of numbers.

b. Find the range of the following set of numbers.

11, 13, 13, 12, 11, 12, 13, 10, 14

A.) The mode is the number occurs most frequently...in this case the number 13 appears 3 times. Therefore mode = 13

B.) The range is the difference between the lowest value and the highest value...
LV = 10
HV = 14

Range = 14-10 = 4
