Compute and Compare Means and Standard Deviations
This product includes a lesson plan with worksheet and answer key aligned with the common core. Review how to compute and interpret the mean and standard deviation from raw data. Students also learn how to compare populations’ center and spread using the mean and standard deviation, respectively, and how to summarize their conclusions. Also covers common student questions about standard deviation: why use squares instead of absolute values? Why divide by n-1 instead of n? The worksheet can be used as an in-class handout or as homework. Questions assess statistical reasoning as well as mechanics.
