Measures of Tendency

Find the mode of the data set, Identify the outlier, and find the mode excluding outliers:

100, 100, 100, 20, 120, 90.

• 110, 120, 100

• 100,100, 100

• 20, 100, 20

• 100, 20, 100

79, 69, 81, 73, 38, 86, 68

• 70.6

• 5.9

• 76

• 5.4

4, 6, 3, 4, 3, 6, 24

• insufficient information to conclude

• increases

• decrease

• does not change
