Histogram Key Rules: 1. Bars touch because data is continuous. • 2. Each bar spans an equal interval (bin). • 3. Height shows frequency (count).

Skill 1: Read Frequencies & Intervals
Scenario A: Daily Reading Log
Grade 6 Daily Reading Time
12 9 6 3 0 0–14 15–29 30–44 45–59 60–74 Reading Time (Minutes) Students
1. What interval represents the peak (most frequent) reading time?
Interval:
Frequency:
2. How many students read for fewer than 30 minutes per day?
Number sentence & answer:
3. How many total 6th-grade students were surveyed in all?
Total:
Explain how you found it:

Skill 2: Answer Real-World Data Questions
Scenario B: Weekend Screen Time
Weekend Screen Time (Hours)
16 12 8 4 0 0–2 h 3–5 h 6–8 h 9–11 h 12–14 h Screen Time (Hours) Students
4. The health guideline recommends no more than 5 hours of screen time on weekends. How many surveyed students met this recommendation?
Calculation & answer:
5. Can you determine from this histogram the exact number of students who used screens for exactly 7 hours? Why or why not?
6. What fraction or percentage of the 40 total students logged 9 or more hours of screen time?
Fraction / Percent:

Skill 3: Compare Histograms Between Groups
Name:
Two middle school grades recorded their nightly sleep duration on school nights (50 students in each grade). Examine both distributions below to compare their shapes, peaks, and spread.
Distribution A: 6th Graders (N = 50) Peak: 8–8.9 h
24 18 12 6 0 6–6.9 7–7.9 8–8.9 9–9.9 10–10.9 Nightly Sleep (Hours)
Distribution B: 8th Graders (N = 50) Peak: 7–7.9 h
24 18 12 6 0 6–6.9 7–7.9 8–8.9 9–9.9 10–10.9 Nightly Sleep (Hours)
7. Compare the peaks (centers): Which interval has the highest frequency for each grade?
6th Grade Peak:
8th Grade Peak:
8. Compare the proportions: How many students in each grade sleep at least 8 hours per night?
6th Graders (8+ hrs):
8th Graders (8+ hrs):
9. Shape & Spread Analysis: How does the overall distribution change from 6th grade to 8th grade? What does this tell you about their sleep habits?
Part 4: Data Sleuth • Claim Evaluation
Justify With Evidence
“Maya claims: ‘Because the 7–7.9 hour bar in 8th grade is taller than any single bar in 6th grade, 8th graders must get more total hours of sleep overall.’”
10. Is Maya’s claim correct or incorrect? Use numerical evidence from both histograms to explain why.
Self-Check: I can read interval frequencies I can compare two histograms I can justify claims with data
