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.
Introdution to
Chance Models: Students are led through the first example in
Chapter 1 (Can Dolphins Communicate?) as they discover the logic of
inference using a single proportion. While building on their own
intuition, they use coin flipping to model a null distribution and then
speed up the process with the use of an applet.
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.
