Practice Test 5

The dot plots show the number of pages read in a week by two reading groups.

Use the dot plots to estimate each group’s center (mean or median) and compare the difference in centers to a typical spread (about how far the points are from the center).

Which description best matches the visual overlap?

The dot plots compare the number of text messages sent in one day by two groups of students.

Estimate each group’s center and a typical spread from the dot plots. Then decide whether the distributions show high overlap, noticeable separation, or are mostly distinct.

Which choice best describes the overlap?
