3. Main Idea/Vocabulary I will choose appropriate scales and intervals for frequency tables. scale interval

4. Example 1 Make a Frequency Table Choose an appropriate scale and interval size for the data. Then make a frequency table.

5. Example 1 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, record the number of caps in each category. Write the total number of tallies in the frequency column.

7. Example 2 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.

8. Example 2 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.

9. 1.A 2.B 3.C 4.D Example 2 Which statement best describes how the data is distributed among the intervals? A.The cost is mostly in the 15-19 interval. B.More than half the data is contained between a cost of 0 and 9. C.More than half the data is within the 10-14 interval. D.None of the values are $0.
