Chapters 1 – 3: Sampling techniques, Measures of Center, Measures of Dispersion, Graphs, etc.
This lab has several data sets the students can use: lab 1
A handout simplifying the sampling techniques: Sampling techniques handout
A handout leading students through the mean from a frequency table, then the standard deviation: mean and standard deviation
You also might like more on the subject of bias, to go with the sampling techniques handout: types of bias. This would be to use in your own lecture, not to hand out to students.
These two quizzes cover the first three chapters. If you would like to use them, please change the numbers. Note: many instructors like to give out two versions of each quiz or test, so that students who are sitting next to each other have two different versions. This is easy enough to do by changing the numbers slightly, or the order of the questions.
If you did not choose to emphasize questions of bias, you will want to omit those questions.
