A stem and leaf plot is a special table where each data value is split into a 'stem' (the first digit or digits) and a 'leaf' (usually the last digit). It helps to organize data and show its distribution.

1. In a stem and leaf plot, the 'stem' represents the leading digit(s) of a number, while the 'leaf' represents the   digit.

2. Stem and leaf plots are useful for displaying the   of a data set.

3. A   is essential for understanding the values represented in a stem and leaf plot.

4. Create a stem and leaf plot for the following set of data representing the scores of students on a math quiz:

Data: 72, 85, 91, 78, 65, 88, 95, 73, 80, 68, 92, 75, 83, 70, 90, 77

Use the following stem and leaf plot to answer questions 5 and 6.

Key: 1|5 = 15

Stem | Leaf

1 | 5 8

2 | 0 1 3 3 7

3 | 2 4 4 6 9

4 | 0 1 5

5. What is the lowest value in the data set?

6. How many data points are in the 30s range?

7. The following data represents the heights (in cm) of a group of 15 students:

152, 161, 158, 170, 165, 155, 172, 168, 150, 163, 175, 160, 159, 166, 171

First, construct a stem and leaf plot for this data. Then, find the median height.

Median height:  

8. A stem and leaf plot is most effective for visualizing very large datasets (e.g., thousands of data points).
