INFORMATIONAL VIDEOS
 
 
 

The following informational videos were prepared to give an idea of how we use randomization and simulation techniques in our introductory statistics curriculum.

  • Chance Models: In this introduction to chance models we take a quick look at how we introduce inference during the first week of the semester. This is done by testing a single proportion. At this point, we do not use traditional statistics terminology like null hypothesis or p-value. That will come in the next section.
  • Two Proportions: This video shows a simulation-based method in statistics that can be used to test two proportions. These tests are sometimes called randomization tests or permutation tests.
  • Two Means: In this video we show how to do a simulation-based test for two means taken from independent samples. This test is quite similar to that of testing two proportions.
  • Paired Data: A simulation-based method for testing paired data is shown in this video. Students at this point would have seen tests for a single proportion, single mean, two proportions, and two means from independent samples.
