### QUESTION 1 of 10

This worksheet is about the three different types of averages and the range of a set of numbers.

Averages

Mean

Add the values and divide this total by the number of values there are.

Median

Find the middle value when you place the values in ascending order.

If there are two middle values, find the mean of these two middle values.

Mode

Find the most frequently occurring value or the most popular value.

Range

This is not an average.

Subtract the smallest value from the largest.  This is the range.
