Let me start with the comparison between the frequentist ANOVA in R and JASP. While JASP, by default, uses Type III sums-of-squars, the function stats::aov() uses Type I sums-of-squares. If you use the same sums of squares, you will see the same re…

If I may add my two cents: As far as I understand, you would like to quantify the relative evidence (i.e. Bayes factor) for the effect across all studies, correct? I, too, would suggest a joint analysis of the raw data. Given that you are combining …

Is this a typo? I assume you mean center at 0 for indifference? Yes, this was supposed to say When you center your ratings at 4, you are now estimating the difference between the decision categories, for indifferent agreement ratings and I hoped it …

The inference about the main effect changes because changes to the coding change the question you are asking. Remember that the main effect estimates the difference between the decision categories, when the agreement rating is 0. If you look back at…

Hi Mikel, the scaling parameter r is different between t-test and ANOVA because the underlying model parameterization is different. This had me confused at one point, too. See this thread for details. Best, Frederik

Sorry, I only just saw your reply, which gives both the frequentist and the matched model result (which, IMHO is preferable to averaging across all models). It's all pretty consistent: The data provide almost no evidence regarding the Task x Load in…

Hi MikJ, I don't have much to add, but maybe some additional comments help to better understand what you are seeing. I agree with EJ that the two tables paint a fairly consistent picture. I assume that you are worried that when you compare the two b…

I wonder if this discrepencies may also be related to the different model comparisons that the frequentist and Bayesian ANOVA do by default. This could be the case if, (1.) you used the default settings for both analyses (which are not equivalent), …

Thanks, you beat me to it. :smile:

Hi Kristel, I found these blog post by Richard really instructive: * http://bayesfactor.blogspot.de/2015/01/multiple-comparisons-with-bayesfactor-1.html * https://bayesfactor.blogspot.de/2015/01/multiple-comparisons-with-bayesfactor-2.html If I u…

Hi Richard, sorry for the late response, I missed your reply. To answer your question: No, it is entirely possible that the flexible model holds for some materials but the restricted model for others. I don't necessarily assume that the outcome fo…
