How can I construct a stem and leaf plot with the midterm test scores of the seventh-period typing class with the list below?
77, 93, 91, 74, 65, 68,97, 88,59,74, 83, 85, 72, 63, 79
Since this is not my area of expertise, I searched Google under the key words "stem and leaf plots" to get this:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
To construct a stem and leaf plot with the midterm test scores of the seventh-period typing class, you can follow these steps:
1. Identify the range of your data: Find the minimum and maximum test scores. In this case, the minimum score is 59, and the maximum score is 97.
2. Determine the stems: The stems represent the tens place of the test scores. Write down all the unique tens digits from the range of the data. In this case, the unique tens digits are 5, 6, 7, 8, and 9.
3. Determine the leaves: The leaves represent the ones place of the test scores. Write down all the ones digits for each stem, placing them in ascending order. For each stem, find the test scores that have that same tens digit and write down their ones digits. In this case, the leaves would be as follows:
Stem 5: 9
Stem 6: 3, 5, 8
Stem 7: 2, 4, 4, 7, 9
Stem 8: 3, 5, 8
Stem 9: 1, 7
4. Construct the stem and leaf plot: Using the stems and leaves you determined, construct a simple chart with stems on the left and leaves on the right. Align the corresponding leaves with their respective stems.
The stem and leaf plot for the given midterm test scores would look like this:
5 | 9
6 | 3 5 8
7 | 2 4 4 7 9
8 | 3 5 8
9 | 1 7
Now you have successfully constructed a stem and leaf plot for the midterm test scores of the seventh-period typing class.
