Parametric and Nonparametric Statistical Tests

This video explains the differences between parametric and nonparametric statistical tests. The assumptions for parametric and nonparametric tests are discussed including the Mann-Whitney Test, Kruskal-Wallis Test, Wilcoxon Signed-Rank Test, and Friedman’s ANOVA.

This was much easier to understand than reading it myself. I wish every class would have videos like this. Much of the time I can read things over and over and it just doesnt stick until someone explains it to me. Very helpful.

Dr. Grande- Thank you for taking the time to walk through these foundation concepts a little more slowly. Very helpful for those of us who have not had a stats course before! -Joshua Kreimeyer

The table at 5:45 will be a good reference for me to look back on as I am trying to remember the different tests within Parametric Tests and Nonparametric Tests.

I have had confusion concerning this 2 items for over a year now. I'm just relieved after watching this video.
Thank you so much.

just came up with 2 acronyms to memorize both the non parametric and parametric tests so i thought I'd share both because they seem to help me: for parametric IPOO (Independent t-test, One-way ANOVA, One way repeated measures) for non paramettic would be: Mann Will Krush Fries. (Mann Whitney test, Wilcoxon-Signed Rank test, Kruskal-Wallis ANOVA, Friedman's ANOVA). Hope this helps :)

This video provided clarity between parametric and nonparametric, I found it especially helpful when determining which to use for my current research proposal.

The description of what the requirements are for using a parametric test is very helpful.

I like the way you explain stats. Very clear and easy to understand.

Dr. Grande, Warm thanks for your detailed explanations of Parametrics and Nonparametric tests.

[kathyglass]

Thank you Dr Grande. You got me through advanced statistics for my doctorate. I'm just at the edge of my ABD. Thank you!!!!

[clairejuszczak]

I have never really talked about nonparametric tests in my statistics classes in the past. Great explanation of what they are and what tests are used.

[elizabethadair]

Really informative as we move forward with our dissertations and of course comps!

[vanessagraham]

I don't know that I've ever had this explained this way before but it definitely helps understand the difference between the tests, particularly as it relates to the assumptions of each.

[AnnaLaura]

I am new to this topic of parametric and nonparametric, I will definitely have to watch this a few more times to get it down.

Thanks Dr. Todd. I was getting really confused from the text and really appreciate your lecture. :)

[kyarapanula]

I was looking for an extensive video on the various tests and their purpose given to specific research design. Thank you for starting this ongoing conversation!

[aussiebreezekorb]

Another good video that explains what tests to consider when approaching a research proposal.

[carolkirby]

Very  helpful to have the design features and assumptions together and to have a comparative table of corresponding parametric and nonparametric tests.

[richaudsley]

This was a great precursor to reading out text on Parametirc and Nonparametric tests. Thanks

[sarahburrous]

All the examples and criteria are good to know when choosing either a parametric or nonparametric test. The final slide is a useful comparison to know the correlation between the tests.
