Down the River
This activity has students surveying by hand using different methods (e.g., systematic, stratified). Highly recommended. This should take about 50–60 minutes to complete and discuss.
Sampling distributions & confidence intervals
Polling Project
In this project, students will find a real poll and analyze it for the credibility of its methods. Give the students a few days to find their poll, then a couple of days to analyze it.
Chapter 6 Practice Quiz
In this practice quiz, students will explain why random sampling works, what confidence intervals mean, and practice constructing confidence intervals. This should take 40–50 minutes to complete.
Stratified Sampling Worksheet
In this worksheet, students will calculate overall p-hats and x-bars from stratified samples. This worksheet optionally contains the formula for the variance and standard deviation of stratified samples. This should take 20–30 minutes.
Confidence Intervals Worksheet
In this worksheet, students will calculate confidence intervals for proportions and for means. This should take 50–60 minutes.
Rolling Dice Activity
In this activity, students will think about the distribution of 1 die, 2 dice, 3 dice, and 4 dice. The point of the activity is that as the sample size increases, the sampling distribution looks more Normal. This should take 40–50 minutes.
Randomization Activity
In this activity, students will try to fake a list of random numbers. The teacher will try to guess which random numbers are real and which are fake. This should take 10–15 minutes.
Chapter 7 Quiz (Version B)
In this quiz, students will be assessed on different sampling methods (e.g., stratified, cluster), non-response bias, and various real-world difficulties, like the method of communicating with people. This should take 30–40 minutes to complete.
Chapter 6 Quiz (Version B)
In this quiz, students will be assessed on their knowledge of why random sampling works, what confidence intervals mean, and how to construct confidence intervals. This should take 40 minutes to complete.
Chapter 7 Quiz (Version A)
In this quiz, students will be assessed on different sampling methods (e.g., stratified, cluster), non-response bias, and various real-world difficulties, like the method of communicating with people. This should take 30–40 minutes to complete.
