8.1. Basic Graph Types http://www.ck12.org

The graph shown above is a pie chart. The slices of the pie represents homework, music, meals, sleep, school, and
work, respectively. In other words, the data that the slices of the pie stand for are not numbers. Therefore, the pie
chart represents categorical, or quantitative, data.

Practice

1. In the table below, match the following types of graphs with the types of variables used to create the graphs.

TABLE8.1:

Type of Graph Type of Variable

a. Histogram _____ discrete

b. Stem-and-leaf plot _____ discrete

c. Broken-line graph _____ discrete

d. Bar graph _____ continuous

e. Pie chart _____ continuous

2. In the table below, match the following types of graphs with the types of variables used to create the graphs.

TABLE8.2:

a. Broken-line graph _____ qualitative

b. Bar graph _____ numerical

c. Pie chart _____ categorical

d. Stem-and-leaf plot _____ quantitative

e. Histogram _____ numerical
