Test of Normality

Discuss statistics related things

Whether one sample or two samples are available, the Shapiro-Wilk normality test gives the same result with Jamovi.

I propose to you, when you have two samples, to perform the normality test not on the scores x_ {ij} but rather on the intra-group differences (x_ {ij} - \ bar {x} _j).

Thanks again for your wonderful software.

yes, i've been meaning to raise this issue for a while. a lot of software does it on the group as a whole (inc. jamovi), which doesn't make any sense.

great if you could create an issue on our issues page:


with thanks
