#### Answer

$\quad$ $\qquad$ mean $\quad$ median $\quad$ mode Samuel $\quad$ 22 $\qquad$ 19.5 $\qquad$ 22 Sticker $\quad$ 22 $\qquad$ 22 $\quad$ $\qquad$ 22 Both sales representatives averaged 22 sales per week for those 8 weeks. The median is 19.5 for Samuel and 22 for Sticker. We would expect 19.5 sales from Samuel and 22 sales from Sticker each week. Samuel’s and Sticker’s sales have a mode of 22 for both. Going by the mode we expect 22 sales from each representative for each week.

#### Work Step by Step

For the measures of central tendency the difference is as follows: The median is the middle number in a list of numbers. Half of the numbers in the set are bigger than the median; half of the numbers are smaller. The mode is the most common figure in a list of numbers. It is the number that appears most frequently.
