Videos and lessons to help Grade 7 students learn how to use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations. *
For example, decide whether the words in a chapter of a seventh-grade science book are generally longer than the words in a chapter of a fourth-grade science book*.

Common Core: 7.SP.4

- I can make informal comparisons of data about two populations.
- I can compare two sets of data using measures of
center (mean, median, mode) and measures
of variability (MAD and IQR).

Sarah wanted to figure out if she did better on tests by studying 2 more hours or by sleeping 2 more hours. She charted her results for 10 different tests. Based on the data, should Sarah study more or sleep more the night before a test?
