Lesson Plan

Describe a distribution's shape, center, and spread as statements about the real-world quantity being measured

Name the direction of skew correctly (skew points toward the tail)

Interpret differences in center and spread between two or more data sets in the context of the situation

Explain how an extreme value (outlier) affects the mean and standard deviation differently from the median and IQR, and how that changes the conclusion

Decide and justify whether an outlier should be kept or removed, recognizing that outliers may be errors or legitimate rare values
