Free Printable Mean Worksheets for Class 6

In 6th grade, Common Core formally introduces statistics. The mean is no longer just a calculation; it is taught as a measure of central tendency (6.SP.A.3) used to summarize a data set with a single number. The focus shifts to understanding what the mean tells us about the data's distribution.

Introduce it alongside the median. Present students with different data sets—some symmetrical, some skewed—and have them calculate both the mean and the median. This leads to a powerful discussion about which measure better represents a 'typical' value in different situations.

A key misunderstanding is not recognizing how outliers affect the mean. Students may calculate it correctly but fail to see that in a skewed data set, the mean can be a misleading measure of center. They also may not understand that the mean does not have to be one of the values in the data set itself.

Move beyond simple calculation with problems that require interpretation. Ask questions like: 'The mean of this data is X. What does that tell you about the data set?' or 'If we add an outlier to this data, how would you expect the mean to change?' These questions promote statistical thinking.

This worksheet can be used for independent practice, homework, or as a quick formative assessment. You can host it as a digital quiz on Wayground for automatic grading or print the PDF for students to complete on paper. For printed work, use the Wayground for Teachers app to scan and grade submissions efficiently.

Challenge them with problems involving a missing data point. For example: 'A student has scores of 85, 92, and 88 on three tests. What score do they need on the fourth test to have a mean score of 90?' This requires them to work backward and use algebraic reasoning.
