? Name 17.1 Essential Question Unlock the Problem A frequency table is a table that uses numbers to record data about how often something happens. The frequency is the number of times the data occurs. Example 1 Frequency Tables Tony kept a table of the number of minutes he read during a 15 day period. He wants to represent this data in a frequency table. Make a frequency table using the data from the table. How do you make a frequency table from data that is given to you? Tony s Reading Times (minutes) Data Analysis.9.A MATHEMATICAL PROCESSES.1.C,.1.D,.1.E 30 60 30 90 30 10 60 60 30 90 10 10 90 60 30 Make a frequency table. STEP 1 List the number of minutes from the Tony s Reading Times table in the Minutes column of the frequency table. STEP Record the frequency of the number of minutes from Tony s Reading Table in the Frequency column. Complete the frequency table. How would the data in Tony s table change if he recorded the number of minutes he read during a 0 day period instead of a 15 day period? Explain how the frequency table would change to show the new data Tony recorded during 0 day period.

Example Jasmine went for a walk each day. She recorded the distance she walked in a table. Use the data in the table to make a frequency table. Distance Walked (miles) Make a frequency table to represent the data. STEP 1 List the distances that Jasmine walked in the Distance column of the frequency table. STEP Record the frequency of each distance from the Distance Walked table in the Frequency column. Complete the frequency table. Distance Walked (miles) Distance Frequency Explain how creating a frequency table whose data is in fractions is similar to creating a frequency table where the data is in whole numbers. Share and Show 1. Use the data in the table to complete the frequency table.
