GUIDED PRACTICE for Example 2
MULTIPLE REPRESENTATIONS The following data show the numbers of letters in students’ names. Use the data in Exercises 3–5.
6, 5, 4, 4, 5, 3, 9, 8, 6, 4, 3, 4, 7, 5, 4, 3, 8, 4, 9, 3
3. Make a frequency table of the data.
4. Make a line plot of the data.
5. Use it to find out whether more students have names with 3 letters or names with 7 or more letters. Describe which display you choose and how you use it to answer the question.
