High School

Plot a stem-and-leaf diagram and a histogram for the following data:

Weights of students in class (in lbs.): 120, 135, 100, 145, 160, 180, 190, 200, 120, 210, 180, 137, 180, 125

2. Describe the shape of this data.

Answer :

To plot the stem-and-leaf plot, we need to take the digits of tens in the leaf and the digits of ones in the stem. The final result of the stem-and-leaf plot looks like the table below:

Stem Leaf

100 0 1 3 5

125 0 1 2

137 0 1 8

145 0 1 6

180 0 9

190 0 1 5

210 0 2

In the histogram, the data will be divided into classes. Since the data ranges from 100 to 210, we can create classes that are about 10 units wide. The first class will be from 100 to 109, the second class will be from 110 to 119, and so on. The histogram of the data is shown below:
