jamovi

This should do what you want?

I'm not aware of MDC and haven't stumbled across it when looking at the main packages in jamvoi, and so it might not (yet) be included. However, the two sources you cited above stated that they calculated MDC according to the following (respective) formulae: = SEM × 1.96 × √2 = SEM × z-value × √2 Ac...

[/quote] Do you know how I can use standard deviation or standard error in bar plot instead of this default setting in Jamovi? [/quote] You don't have the option of choosing the source of the error bars in the 'Descriptives' route - but if you were to choose a oneway ANOVA or RM ANOVA then under the...

The size of the error bars do not seem to correspond to either the SD or SE values in your table, and so they are most likely 95% CI (this is the default setting for t-tests and ANOVA). Re-run your descriptives with the 95% CI option ticked and you'll probably see these match up...

I think the problem is that your code is expecting data to be present (either above or below a set value) - however, as these cases have an absence of a value, your code doesn't take this into account and so the outcome is left blank. Try including a reference to 'ignore_missing' or such like in you...

Hi, When I run Descriptives all my variables show missing value, but no cells were empty. Is something wrong with my dataset, How to solve this problem, and does it affect all the analysis? Thanks At a guess, at one point you probably had 70 rows of data (maybe as a result of copy/paste?) and then ...

I got the answer from other forums. I missed something big. Because the relationship between the IV and the DV is negative, the predicted value should have a negative relationship with the IV. Sorry, it is not a bug. I found a big missing piece in my understanding. As you've probably realised, the ...

Whilst there are undoubtedly the odd statistical test (or rather test options) here and there that jamovi offers over and above SPSS, it is my personal view that the major difference/benefit stems from the more elegant interface it possesses. Gone are the days of analyses/options being buried in a s...

The correlation could only really be done if your second variable was ordinal (not nominal) and so I would assume that you are indeed more interested in differences in mean 'first survey' scores based on the categories from your second variable (is this correct?). If so, I'm not clear on why you app...

Can you show your data file here? It sounds as though you either want to run a correlation between your two surveys, or that you are using the second 'survey' as a grouping variable to see if these 'groups' have a significant difference in scores on the first survey. If you have too few participants...
