There are several baskets on a table, and each basket has a certain number of strawberries. Here are three data displays showing the number of strawberries in each basket.
Dot plot from 0 to 20 by 1’s. Strawberries in a basket. Beginning at 0, number of dots above each increment is 0, 0, 0, 2, 0, 1, 0, 3, 2, 0, 1, 4, 3, 6, 1, 6, 5, 3, 0, 0, 0.
There are 4 baskets that contain 11 strawberries.
The range of the number of strawberries in baskets can be found using any of the three data displays.
The number of baskets of strawberries can be found using only the dot plot.
The interquartile range can be found using the dot plot or box plot, but is easiest with the box plot.
The total number of strawberries in each of the baskets can be found only from the dot plot.
Complete the table to show the frequency of baskets containing strawberries in each range. Which representation did you use?
| number of strawberries | frequency |
|---|---|
| 0–6 | |
| 6–12 | |
| 12–18 |
