Question

Create a histogram for the data set. Click and drag on the horizontal axis to adjust the heights of the bars.

81, 65, 2, 24, 25, 44, 97, 12, 38, 37
how many go in each

Answer 1

I can’t draw the interactive histogram here, but I can give the counts per bin so you can place the bar heights. Two common choices:

1) Ten bins of width 10 (0–9, 10–19, …, 90–99)
- 0–9: 1 (2)
- 10–19: 1 (12)
- 20–29: 2 (24, 25)
- 30–39: 2 (37, 38)
- 40–49: 1 (44)
- 50–59: 0
- 60–69: 1 (65)
- 70–79: 0
- 80–89: 1 (81)
- 90–99: 1 (97)

(Heights: 1, 1, 2, 2, 1, 0, 1, 0, 1, 1)

2) Five bins of width 20 (0–19, 20–39, 40–59, 60–79, 80–99)
- 0–19: 2 (2, 12)
- 20–39: 4 (24, 25, 37, 38)
- 40–59: 1 (44)
- 60–79: 1 (65)
- 80–99: 2 (81, 97)

(Heights: 2, 4, 1, 1, 2)

Which binning would you like to use, or do you want a different bin width?
