Comparing Distributions
Students have explored the important numerical measurements of center, shape, and spread in evaluating data.
In this unit, they will put their knowledge of these three measures together with the visual display to compare and contrast data from different distributions.

Students will  learn how to numerically compare  distributions through the coefficient of variation, and will learn how to evaluate relative positions using  Z-scores.
