A coffee shop monitored the number of cups of coffee sold each day. What is the mean of the numbers?
Day | Number of cups
Saturday | 16
Sunday | 14
Monday | 16
Tuesday | 21
Wednesday | 23
Read the numbers from the table.

16, 14, 16, 21, 23

First, count how many numbers are in the group.

There are 5 numbers.

Now add all the numbers together:

16 + 14 + 16 + 21 + 23 = 90

Now divide the sum by the number of numbers:

90 ÷ 5 = 18

The mean is 18.
