# Ways of Thinking: Make Connections

Take notes about the different approaches your classmates used to describe and make conclusions about the data.

As your classmates present, ask questions such as:

- Which value is a better indicator of the typical score—the mean, median, or mode? Why?
- Where is the data clustered on the line plot? What is the range of the data?
- What does this information tell you about the data, and possibly the sample?
- What is a typical score for Class A? For Class B?
- Based on the line plots, which class performed better on the test? How do you know?
- Are either of these samples a random sample? Explain.
- Would you consider the combined results of the two samples to be a random sample?
- Are the combined class results closer than the separate class results to showing how all the seventh graders in the district did on the test? Explain.
