Very informative video! I got a data (sample size more than 100) where the z value of skewness and kurtosis fits into the range of +3 and -3, which suggest the data is normal. But the kolmogorov smirnov test suggests the test is non normal. What inference or conclusion can be drawn from this? is the data normal or non normal?

I had to use spss previously, didn't like it. have to use it again... still don't like. no choice in the matter though. i have a Q regarding it as we will use qualtics to do a study, and spss for the data. which do you build the 'questions' for the qualtric questionnaire in? you listed the colors, can those colors in name under variable view be individual questions?

Thank you so much for this video! I have a quick question: is it possible to do a spearman's rank correlation test with an ordinal variable (1-7 scale) and a nominal variable, for example age that have been sectioned into groups? If not, is there a way to see if there are any correlations between these two variables? Thanks again!
@virginiawickline26098 ай бұрын
Hi! My pleasure. Nominal variables should not be used with Spearman. If age has been chunked into 3 or more groups, it would be an ordinal variable as well and Spearman could be used. If age is just two groups, you would want an independent samples t-test or a point-biserial correlation.

So what about ordinal data? Scale responses, agree-disagree? How do I make an "appropriate" graph for those? Do I just mark those as scale-type data? You confused me xD
@virginiawickline2609 Жыл бұрын
From my understanding, statisticians disagree here. Some say it is OK to use a histogram for ordinal data (see, for example, sphweb.bumc.bu.edu/otlt/mph-modules/bs/bs704_summarizingdata/bs704_summarizingdata4.html#:~:text=When%20one%20is%20dealing%20with,categories%20have%20an%20inherent%20order). Others say you should not use a histogram for ordinal data and should use a bar chart or box-and-whisker plot instead (www.uni-bamberg.de/fileadmin/eng-ling/fs/Chapter_19/411Frequencydata.html).

Thanks a lot, Madam, for your lovely explanation. My question related to the normality: Can we run a normality test (Shapiro or k-s test) to make a decision rather than usage figures, because for beginners like me, I can not judge on the normality from figure or you must decided on figures. Thanks in advance
@virginiawickline2609 Жыл бұрын
My pleasure! Absolutely a normality test is appropriate. I run out of time to also teach this during my class (which is the primary audience for this video), but if I were doing it myself for research, I would rely on a K-S (Komolgorov-Smirnov) test myself.

Hi! What is the best way to plot a spearman correlation so that we clearly see the information that it is giving? I think it's not useful to plot a regression line as it depends on outliers, while the spearman correlation doesn't.
