The median is a more appropriate measure of central tendency when there are extreme

values in the data. For example, average Income is usually a median, rather than a mean,

because of the extremely large incomes of a few individuals.

The third measure of central tendency is called the MODE. The mode is the MOST

FREQUENTLY occurring observation in a group of data. For example, given the set of data: 38,

19, 27, 25, 27, 26, 19, 27, 22, we see that the observation 27 occurs 3 times. The mode for this

set of data is 27. Find the mode for the following three samples:

Sample A: 22, 29, 22, 7, 34, 14, 17 ________

Sample B: 31, 2, 8. 22, 19, 28, 13 ________

Sample C: 22, 7, 29, 34, 22, 14, 31, 7 ________
