Below is a subset of the data described here. Create a grouped frequency table for these data, using seven groupings.

1, 5, 3, 9, 13, 0, 18, 15

3, 3, 5, 7, 7, 7, 11,3

12, 20, 16, 4, 17, 15, 16, 10

6, 8, 8, 7, 3, 17

1. Create a histogram of the grouped data from (e).
2. Describe how the data depicted in the original graph and the histogram you created in part (f) are distributed.
3. Use the data in part (e) to create a stem-and-leaf plot. For each score, use the first digit for the stem and the second digit for the leaf. For values under 10, use 0 as the stem and single digit for the leaf.
4. Refer to the stem-and-leaf plot you created in (h). Do these data reflect a floor effect or a ceiling effect? Explain your
