- Complete the frequency distribution table by counting how many data points fall into each interval.
- For 1–3: Count values 1, 2, 3 → 6 occurrences
- For 4–6: Count values 4, 5, 6 → 7 occurrences
- For 7–9: Count values 7, 8, 9 → 8 occurrences
- For 10–12: Count values 10, 11, 12 → 6 occurrences
- For 13–15: Count values 13, 14, 15 → 4 occurrences
- For 16–18: Count values 16, 17, 18 → 3 occurrences
- Total number of data points is 34 (sum of all frequencies).
- Construct a bar chart with intervals on the x-axis and frequency on the y-axis. Each bar’s height corresponds to the frequency of its interval:
- Bar for 1–3: height 6
- Bar for 4–6: height 7
- Bar for 7–9: height 8
- Bar for 10–12: height 6
- Bar for 13–15: height 4
- Bar for 16–18: height 3
Parent Tip: Review the logic above to help your child master the concept of histogram worksheets.
