Here are some questions to start discussion:
- Regarding the data summarized in a bar chart regarding % of drivers donating organs in the various European countries, was it collected through a study or an experiment? Explain.
- According to the video, what was the difference between the countries with high percentage and the countries with low percentage of organ donors?
- Sketch a possible experimental design diagram for the experiment involving doctors and pain medication hip replacement.
- Sketch a possible experimental design diagram for the experiment involving subscription to the Economist. What was the population of interest? To what extent should the conclusion be drawn?
- Sketch a possible experimental design diagram for the experiment regarding ugly Tom and ugly Jerry. Was there a control group in this experiment (based on just the information provided)? Explain.
- What bias is being investigated in the video?
Here are some screenshots from the video to set context for question 4:
This is an AP Test style sample answer to question 4:
Lastly, check the conditions and perform an appropriate hypothesis test using the data from the video. Here's the screenshot with the results:
That's all I have come up with for now. I would appreciate suggestions for improvement.
This is one of the more memorable videos for kids, especially the ugly Tom and ugly Jerry's effect on Tom and Jerry respectively. Students got to see examples of experiments and how they were designed so that conclusions can be drawn. I think it would be even better if the students also got to read the original papers, especially if the papers use the statistical methods learned at the high school level.
