Refer students to the different data representations
used in this lesson: picture graphs, bar graphs, and
data tables.
- How does a picture graph show data? (Responses
will vary. Possible responses: The one variable is
shown in words and the other in pictures. It is
like a bar graph but rather than coloring in a bar,
the numbers are represented with individual pictures.)
- How does a bar graph show data? (Responses
will vary. Possible responses: It is like a picture
graph but each quantity is shown by shading in a
bar rather than with pictures.)
- How does a data table show data? (Responses
will vary. Possible response: Both variables are
shown with numbers or words.)
- Which do you like best?
- What type of information can you easily find on a
bar graph? Picture graph? Data table?
