Step 1

Find the data range by subtracting the minimum data value from the maximum data value. In this case, the data range is .

Step 2

Find the class width by dividing the data range by the desired number of groups. In this case, .

Step 3

Round up to the nearest whole number. This will be the size of each group.

Step 4

Start with and create groups of size .

Step 5

Determine the class boundaries by subtracting from the lower class limit and by adding to the upper class limit.

Step 6

Draw a tally mark next to each class for each value that is contained within that class.

Step 7

Count the tally marks to determine the frequency of each class.
