Every Sunday of this year, I plan on focusing on one of the statistical tests featured in the Handbook of Parametric and Nonparametric Statistical Procedures (5th edition) by David J. Sheskin. I will include the following information in each post:
- When would you use the test? What type of research question might the test help to answer?
- For what type of data is the test appropriate? Do you need interval/ratio data, categorical data, etc.?
- Assumptions. What assumptions must be met in order for the test to be accurately employed?
- Process. The steps (and equations) of the test.
- Example. The test carried out with real data.
- Example in R. The R code for the above example.
I’ll start this tomorrow, and while I’ll probably put a little menu button up at the top of my blog homepage to link to all the tests (a thing like a “Statistics Sundays” button or whatnot), I figured I should explain it here, too.
