Lesson 1

Lesson 1 Summary

There are a variety of ways that data can be organized, presented, and summarized. How data is displayed or organized affects what inferences or conclusions can be drawn from the data.

For instance, working with the individual class data sets allowed you to compare the quiz marks for the two classes. This strategy allows you to look at both similarities and differences in the data for the two class results.

Combining the quiz marks for both classes gives you information about student performance on the quiz regardless of which block the quiz was written in.

The conclusions that you are able to draw from examining data are often dependent on how the data is organized, presented, and summarized.

In Lesson 2 you will look at how summary statistics can meaningfully describe a set of data like Mr. Kong’s quiz marks.
