Labs for this unit
- Topics 1.10 to 1.13 Who Can We Generalize To? What Caused It? Read a study, decide whether it used random selection, random assignment, both or neither, and claim only what the design allows.
- Topics 1.5 to 1.9 Shape, Center, Spread A new data set every round. Name its shape, spot outliers with the fences, and decide whether the mean or median is larger.
