6. The table below shows the number of hours students watch TV in one week. Make a histogram of the data. Step 1: Make a frequency table of the data. Be sure to use equal intervals. 6 /// 7 //// //// 8 /// 9 //// 1 // 2 //// 3 //// //// 4 //// / 5 //// /// Number of Hours of TV 1–3 Frequency Number of Hours of TV 15 4–6 17 7–9 17

7. Step 2: Choose an appropriate scale and interval for the vertical axis. The greatest value on the scale should be at least as great as the greatest frequency. 1–3 Frequency Number of Hours of TV 15 4–6 17 7–9 17 2 4 6 8 10 12 14 16 18 20 22 1 - 3 4 - 67 - 9 Hours of TV Watched Hours Frequency
