Stem and Leaf Plot Practice

Stem and Leaf Plot Practice

Read each question carefully and follow the instructions to complete the stem and leaf plots or answer the questions based on the given data.

1. The following data represents the scores of 15 students on a math test: 78, 85, 92, 70, 88, 75, 95, 80, 72, 83, 90, 79, 86, 77, 81. Create a stem and leaf plot for this data.

2. Use the stem and leaf plot below to answer the following questions. Stem | Leaf ---|--- 6 | 5, 8 7 | 0, 1, 3, 5, 9 8 | 2, 4, 6, 6, 7 9 | 0, 1, 3 What is the lowest score represented in the plot?

3. How many data points are represented in the stem and leaf plot above?

4. Using the same stem and leaf plot from question 2, the median score is  .

5. Using the same stem and leaf plot from question 2, the mode score is  .

6. The heights (in cm) of two groups of plants are given below. Create a back-to-back stem and leaf plot to compare the two groups. Group A: 23, 25, 28, 30, 32, 35, 37, 38, 40, 42 Group B: 20, 22, 24, 26, 28, 30, 31, 33, 36, 39
