Answer
MEAN: 12.625
MEDIAN: 12.5
MODE: 12 and 16
Work Step by Step
First, put all the numbers in numerical order from least to greatest:
8, 10, 12, 12, 13, 14, 16, 16
MEAN: To find the mean, add the numbers together and then divide by the number of numbers.
8 + 10 + 12+ 12 + 13 + 14 + 16 + 16 = 101
There are 8 numbers in this set, so divide 101 by 8:
$\frac{101}{8}$ = 101 $\div$ 8 = 12.625
MEDIAN: The median is the middlemost number. Because we have 8 numbers, there is no single middle number. There are, however, two middle numbers. The median is therefore the mean of the two middle numbers. Here, the middlemost numbers are 12 and 13. Our median is (12 + 13) $\div$ 2 = 25 $\div$ 2 = 12.5.
MODE: The mode is the number(s) that appear most often. There are two 12s and two 16s. As these numbers both appear most often, 12 and 16 are both the mode.
