I think if you're going to use Bayesian statistical analysis, you need to inform your audience, at the start, that such analyses are limited in that there's often no available Bayesian option for non-parametric testing.

For a repeated-measures ANOVA , first, you need to get your data into the format illustrated below. Then, I refer you again to the JASP documentation to learn how to do a repeated-measures ANOVA in JASP. https://forum.cogsci.nl/uploads/419/193T9IVSO…

It turns out that there are multiple problems: (1) Note that sums of squares should generally be Type III. (2) Because of an apparent misspelling, you have four word types instead of three: "living", "object", "enviro",…

I would need to see the whole data file, or some facsimile of it.
-
Actually, here's a start, below. (Also, FYI. I'm not sure it's the best thing to call this "R" code, because JASP is embedding within additional R code that the user can't see. So if one were to type these statements into an R console, it …
-
No, not off hand, but maybe I could create a brief one.
-
Personal opinion: While the drag and drop is intended to simplify things for novices, I think in many cases things will turn out better if the novice uses R code.
-
@EJ. I think, yes, you would. But my point is that, suppose the result of multiplication shows that the data are most consistent with Factory 1. One would need to exercise caution and refrain from drawing the further inference that (i) the data are…

To simplify, Given the hypotheses: H1: XY>0 and MZ>0 H2: XY>0 and MZ=0 H3: XY=0 and MZ>0 H4: XY=0 and MZ=0, the data may be more consistent with #1 than with any of the others, but that wouldn't imply that the data are also more consi…
-
@EJ I'm open to being persuaded. For me, I think the categories "John," "Mary, "Amy," "Jim," serve as an organizational aid, but for mathematical clarity, I prefer your originally-worded, four hypotheses. XY>0…

Export Data Computer Save the data as a .csv file. Excel can open it. In Excel, save as a .xlsx file.

I don't know if it's well-known in this particular linguistic expression. But the bottom line is that you need: A data pattern, some mutually exclusive hypotheses, and for each hypothesis, a quantification of the likelihood that the observed data pa…

@Michael_Jasper As I tried to state above, though I've heard knowledgable people argue otherwise, I believe Bayes factor multiplication is for situations in which all of the following apply: (i) you have one set of hypotheses (e.g. R[xy] > 0 and …
-
Greetings Michael, Questions of statistical independence aside, I'm not convinced that this sort of Bayes factor multiplication is capable of addressing your research question. Broadly, the question concerns a conjunction of statistical hypotheses, …

I've never heard of a multiple-response-question feature in spss.
-
No. JASP isn't a survey/data-collection tool. It's a tool for statistical analysis.
-
No problem. Also, I find the following example to be a helpful illustration that the Mann-Whitney U test isn't a test of difference between medians. The two groups have the same median (100), but the Mann-Whitney U test shows that the ranks (of all …
-
I think you can report any or all of those descriptive statistics, despite their disconnect from the Mann-Whitney U. Some people may not like it, though, because they think the Mann-Whitney U is about medians. Whatever you do, you should include an …
-
I believe that the Mann-Whitney U test tells us, given a randomly sampled Value A (from Population A), and a randomly sampled Value B (from Population B), what's the probability that Value A is greater than Value B. So it's neither about means nor m…
-
Hi. (1) I think it would help if you include the estimated marginal means in your post. (2) The post hoc test result doesn't make sense to me: It should be redundant with the main effect of "conditions" in the tests of within subjects eff…
-
Yes, that's right.
-
Hi. I don't think you'll find a standard, straightforward way to do inferential statistics on the frequencies of NON-mutually-exclusive categories. You could filter your data to include only those children whose answers fell in one and only one of t…
-
Select FREQUENCIES, CONTINGENCY TABLES. Make one of your fixed factors the ROW variable. Make the other your COLUMN variable. I think you will see that some cells in the table are missing in that they have a frequency of 0.0. That's not allowed in A…
-
I think a rank-based analysis is fine in these situations as long as one doesn't treat the test as going beyond ranks in any way. The statistical inference concerns whether, in the population, the Group A values tend to rank differently (i.e., highe…
-
@EJ OK. But maybe the situations in which you need non-parametrics the most are when such a transformation is not possible because the two non-normal distributions have different shapes (as illustrated below). https://forum.cogsci.nl/uploads/846/PK…
-
@JohnnyB Thanks. From the paper, I'm seeing that the latent-normal assumption applies when you have ranked data that might well have been normal had they not been converted into ranks. However, I believe a major motivation for performing a Mann-Whit…
-
Also, in JASP as well as any other standard stats package I can think of, the RM ANOVA algorithm does not accommodate missing data. For example, if you have . . . subject#1 trial #1 = 39 subject#1 trial #2 = 33 subject#1 trial #3 = 47 subjec…
-
My recollection from doing RM Measures ANOVA in SPSS is that SPSS always produced univariate output along with multivariate output, and the results for the univariate approach were always identical to the results for the multivariate approach.

Fisher's z = .5 ( NaturalLog[1 + r] - NaturalLog[1 - r] ). So you need to do the Fisher's z transformations after you've used JASP to compute the correlations.
