Stretch: Which Display Tells the Story Best?
I can choose the best data display for a question and read values from a histogram.
🧠 The Big Idea
A dot plot shows every value (good for small data sets).
A histogram groups values into intervals (good for large data sets and showing shape).
A box plot shows spread and the middle 50% (good for comparing groups).
| Test-score interval | 0–59 | 60–69 | 70–79 | 80–89 | 90–100 |
|---|---|---|---|---|---|
| Number of students | 2 | 5 | 9 | 7 | 3 |
✏️ Your Turn
0 of 3 checks complete
1. Using the histogram table, how many students scored 70 or above?
2. You want to compare the spread of scores between two classes. Best display?
3. Which display would best show the shape of 500 students' heights?
💬 Explain Your Thinking
Explain your choice of display for one of the questions:
"I would use a blank because it is best at showing blank."
