Thanks for the video. It is pretty sad excel does not have an Anderson-Darling test for normality built in. I’m a retired guy and miss Minitab.

Agreed. It would be nice for more advanced functionality but that is why we teach R Studio once we get past a first course in statistics.

Hi, Great video! I really feel I am learning about how to check for normality! Question: What should we look for with kurtosis for checking for normality? Thanks.

So if your mean is somehow equal or roughly equal to the mean, then it’s a normal distribution right?

My doubt is that do we have to check normality for every question in the questionnaire or it is overall data.

19:16 So they “have a really good chance to be normal”, but that doesn’t mean that we have proven that the distribution is normal, correct?

At what stage shoud we run a normality test ?

I run a normality test if I am about to run a hypothesis test that needs it as an assumption. Also, if we have normality, then probability rules are clearer.

Hi Joe, My Mode: is # N/A however all my cells have values

A mode of #N/A means you have all unique values so hence no mode. The good thing is that for checking normality you want to focus on the mean roughly equal to the median.
