OBJECTIVE
1. Explain the key difference between parametric and non-parametric tests.
2. Identify three parametric tests.
3. Describe one way we can check to see if it is appropriate to use a parametric test.
INSTRUCTIONS
Scenario: You overslept and did not make it to your GEOG/TOUR 3P22 lecture. When you ask your friends for their notes, they say they no longer go to class since you do such a good job at teaching them. Exasperated, you now have to teach yourself the difference between parametric and non-parametric tests.
Prompt: Answer these three questions:
1. What is the key difference between a parametric test and non-parametric test?
2. What three parametric tests have we covered so far in class?
3. What R command helps you determine if it is appropriate to use these three parametric tests?
You recall reading about non-parametric tests in Rogerson’s Statistical Methods for Geography. Was that in Chapter 6?
