A Gentle Introduction to Non-Parametric Statistics (15-1)

We are now going to look at a special class of tests that give us the ability to do statistical analyses in circumstances when parametric tests just won’t do. They are called non-parametric statistics. Parametric statistics like t tests and ANOVA compare groups using scale-level data. Non-parametric statistics can be used when you only have nominal data.

This video teaches the following concepts and techniques:

Link to a Google Drive folder with all of the files that I use in the videos including the datasets. As I add new files, they will appear here, as well.

I am blown away by the clarity of your videos.

I like explanations like this. I wish statistics courses for used more on understanding the concepts and less on solving endless problems.

Thank you immensely. I am taking Biostatistics, and this helped tremendously!

Where do we find a copy of that Bear hand out?

Excellent video. I would like to clarify a question. Can we use Pearson and regression coefficients when our data do not accomplish the assumptions of parametric tests?

I've read that Person and regression coefficients are parametric tests but I've not found their corresponding no parametric tests.

Thanks so much for the videos. Please i need help on this. i am analysis some data and this is what i want to do using spss. can you help with the procedure?

To measure family sense of belonging, family autonomy, family control and school sense of belonging; a 3- level variable would be created: low, medium, high and the high category used as the reference category. These categories would be derived by scoring each of the responses, summing the scores and assigning the results to each of the categories. For example, the respondent’s social capital indicator ‘school sense of belonging’ would be made up of 6 statements such as: I feel like I belong to this school, I feel lonely at school; I feel like an outsider in my school, other students seem to like me etc. There would be 5 possible response categories and these would be scored as follows: strongly agree (1); agree (2); disagree (3); strongly disagree (4) and don’t know (5). For the analysis, scores would be grouped as: low SSB; medium SSB and high SSB.

Why in the 21st century would one be calculating any statistics by hand?
