Re: Independant Samples t-Test: Assumption Checks?
I believe it's the residuals for the entire model that need no be normally distributed. https://statistics.laerd.com/statistical-guides/independent-t-test-statistical-guide.php#:~:text=Assumption%20of%20normality%20of%20the,give%20you%20the%20same%20result.

Re: seolmatrix
What I've found is that many institutional computers have app blockers that may allow core aspects of jamovi to run while blocking other aspects. I've found that this blocking is especially likely to affect modules. Moreover, I've found seolmatrix to be more affected than any other jamovi module I u...

Re: Contigency tables
Oh. Sorry. However, I think those comparative measures are only computable in situation where the analysis can be conceptualized as comparing two things (to proportions, two ratios, etc.). Thus, they only work for 2 by 2 tables: https://cran.r-project.org/web/packages/chisquare/chisquare.pdf I've se...

Re: Contigency tables
Hi. jamovi's chi square contingency analyses aren't limited to 2 by 2. 3 by 4 works just fine.

Re: Jamovi to support Apple Silicon chips
@jonathan Is there supposed to be a jamovi Version 2.5.x for Windows, or is the new version only for non-Windows platforms?

Re: Comparing a mix of paired and unpaired data?
The quantified parameter needs to be a 'close-enough' approximation to interval/ratio. Most analysts think that the kind of scores you have are close enough. You can adjust for multiple comparisons. You'll need to use something like jamovi's Rj module (or R). See the example code, below: # This code...

Re: Comparing a mix of paired and unpaired data?
Within the context of traditional, well-known statistical analyses, I don't think a "mix of paired and unpaired data" is analyzable in any streamlined way. You have three groups rather than four, and you need to do a set of t tests--most of which will be independent-samples t tests, and on...

Re: scatterplot improvement
@Oavasns From jamovi, I exported the plot as an svg. I then pasted the svg image into PowerPoint, right-clicked the image, and selected "convert to shape". From there I simply deleted the unwanted elements of the image. I notice that PowerPoint messed up the text in the margin. However, Ex...

Re: Comparing a mix of paired and unpaired data?
I have some trouble understanding the data set. Could you produce and share a small, mock data set as an example?
