Find the median of the following two samples:
Sample A: 17, 22, 29, 23, 7, 34 ______________
Sample B: 22, 17, 10,000, 29, 7, 23 _________________

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 ________
