Example 1:Make a Frequency Table

Example 2:Make a Frequency Table

• I will choose appropriate scales and intervals for frequency tables.

• scale

• interval

Make a Frequency Table

Choose an appropriate scale and interval size for the data. Then make a frequency table.

Make a Frequency Table

The data are from 7 to 14. Make the scale from 7 to 14 and the interval size 2. The categories are 7–8, 9–10, 11–12, and 13 –14.

In the tally column, recordthe number of caps in each category. Write the total number of tallies in the frequency column.

Make a Frequency Table

The table shows lunchtime sales for one hour. Make a frequency table of the data. Then write a sentence or two to describe how the data are distributed among the intervals.

Make a Frequency Table

The sales range from $0.99 to $9.21. You could make the scale from $0.01 to $10.00 with an interval size of $1.99.

Most sales were in the $4.01–$6.00 interval.
