Ep073: Self-Expansion Theory Across the Multiverse! Everything Everywhere All At Once (2022)
Precisely what I was searching for. Thank Prof. Swan! Is it possible to test if a variable is a mediator or moderator? For instance, you have shown that anxiety is a mediator. Can we test if anxiety acts as a moderator?
I would caution against this - mediators are third variables and moderators are interactions. These complex regressions are designed to be backed by logic and theory, so you need to have that in place BEFORE you run a model. One should not go back and forth just to see. Further, it really depends on how you’re measuring the variables. In your example, anxiety would not really work as a moderator because of how it is usually measured .
I have difficulty with vision. How did you get that teal circle around your mouse pointer? thank you!
It’s an app for MacOs called Cursor Pro. You can find it on the Mac App Store.

Hello Alex. Thanks a bunch for the help. i am looking for one on one help with double checking some ANOVA results and a power analysis for effect size of the participants numbers. I will pay happily for the help. Cheers.
Please email me or send me a DM on my Discord
Thanks a lot!
Your voiceover is much too fast for me. English is not my first language but I am fluent, yet I struggle to follow what you are saying even at 0.75 speed.
Sorry to hear that. I have to strike a delicate balance or verbosity and timing. Definitely skip around, play/pause, and use the visuals to help you. This is more a tutorial on how to use the module rather than explanation of the statistical concepts. I only scratch the surface of randomization in this video. Happy to chat further through email or Discord DMs if you have questions!
it must be direct to the point when teaching
Thanks for the tip. Sometimes it is difficult when doing a tutorial on screen to maintain a good pace and making sure to get everything in to anticipate questions. You are welcome to create your own teachings, however! You are also welcome to skip around the video or watch another person’s video!
"to give this tutorial a little more.... UMMMPGH" xD
life saver thank you!!
When calculating the SDs at 10:39 in the video, for my between groups factor (2 levels; high autonomy group v. low autonomy group) does it matter if my sample sizes are different for the calculation? Meaning for the formula where you include N do I use my total sample size or the N size per group for each corresponding SD calculation?
@@user-hz6dq9us2jhi does anyone know the answer to this and or could provide a reference ?
Hi does anyone know an answer to this and or reference to provide that I could look into?
This video is helpful!
Love the detailed comparison. You will be impressed with JASP 0.19 I think. It will hit us in 1 or 2 months with massive improvements to recoding etc. I agree with your stance of a tie currently. Both programs have the same number of strong points and weaknesses. The biggest weakness with jamovi I see is, that it does not allow to resort or duplicate analyses and the lack of integrated help files. So I am curious: How do you manage these points?
Very much looking forward to that! For my purposes, resorting analyses isn’t a game changer or breaker. I’ll have to remind myself about the duplication of analyses, because I’m remembering something but my memory might be conflating functionality. If I’m misremembering, I’m not entirely sure it would be a big deal to me either, again a minor point. The help files are huge and some do need to be added. Jamovi does rely on external help from useful others (such as myself), which can be a problem if a user doesn’t know where to look, like Learning Stats with Jamovi. I still give Jamovi the edge in the tie, as I say in the video, because my course are built on its functionality. I also think Jamovi is slightly more intuitive in its GUI and its expansion with modules and R packages.
@@AlexanderSwan yeah, the gui is a bit more explicit. With "learning statistics with jamovi" you mean the book by navarro? Thats a good one, yes, I also use the jasp version of that sometimes (but that one is now a bit outdated, 2019).
Well done, Great, Thanks!
Well done! Great!
it was really really great to take these classes with you sir i am very thankfull to you for these free of cost lectures loved the way of teaching and expressions
Dan is Danielle J. Navarro (one of the authors of LSJ) so mum, not dad.
You’re absolutely right! I recorded this and had been using the data before I realized that.
Can you make a forest plot with "Numbers"?
Not quite; there’s no built-in function like Excel, and you have to massage a scatterplot and customize it.
Nice comparison! What do you think about the machine learning module in JASP? And, is there anything similar in Jamovi?
I don’t do machine learning so I have not looked at either app’s module on that, sorry! Thanks for taking a look :)
I am doing this unit and this one is so simplified
Hi there! really finding these videos helpful in studying for finals, but i'm confused as to how and since when is marijuana is classified as a hallucinogen?
It depends on the strain, how much is used, and effects. I was quite a bit loose on the nomenclature in the video. Cannabis can induce psychosis, so it can induce hallucinations.
Thanks the topic got very clear hope you do a series on positive psychology soon
Nice videos Prof!
Thanks a lot. It was beneficial for me when analyzing. Could you please make a video that includes control variables?
Thanks for the suggestion! I’m not sure but I’ll keep it in mind
It’s 13:12 in South Africa and I’m writing my exam at 15:00 and I’m only coming across this channel now 😭 You’re literally my hope now lol
Can you help for doing three way anova , financial literacy as dependent factor and faculty, education level(higher secondary,bachelor,master), universities as independent variables
What help do you need?
I have a question, I know different analysis options have maximum likelihood to deal with missing data in jamovi but my question is that the liner regression option in jamovi have Maximum likelihood in it setting or background ?
I’m sorry, I’m not following your question - are you asking if linear regression has maximum likelihood?
Obrigada, obrigada , obrigada. Por mais canais ASSIM!
How would one figure out the model-estimated probability
Hello! I am planning a 2x3 within-subjects ANOVA. If I run the within-subjects power test, would I leave group at 1 and measurements at 3 since that's the factor with the larger number of measurements? Or would it be all possible measurements (i.e., 6)? Does this also account for interactions? Thank you!
Look at each of these effects in the literature and base your sample size needs on the smallest predicted effects. Either that or focus on the effect you are most invested in (main effects or interactions). The power analysis should be geared toward one of those, and the rest of the effects will come along for the ride.
@@AlexanderSwan Thanks so much!
how do i activate my voicemod pro? i have the key but cant find where to actiate it

Thank You
You explained everything so well and clearly that I understood everything with my poor knowledge of English. Thank you!
Awesome, I want to get a msc degree and health and positive psychology. Thank you for this video.
0.36 + 0.36 = 0.72
To be sure, this gripe was meant to convey that the episode kept me interested all the way through. Thanks and kudos!
How can you change the order of the two conditions. In a pre-post analysis some variables are plotted in the desired order (Pre - Post) and others in the opposite with no apparent reason.
I’m not sure why things are in different orders. The only thing I can suggest is to make sure everything is in the preferred order in the variable box
what is the meaning of "W"" on the Table ?
That’s the statistic, like t or F or r
Hello thank you so much for this video. But is it possible to do assumptions checks in GLM Mediation Model ?
It is not currently.
Very good, thank you!
Thank you so much! This was very useful, but i have an issue. I am trying to analyse the correlation between 8 variables and the matrix is just incredibly messy. The scaling is all wrong, so i can't see the graphs either, plus I loose the p values for significance. My instructor wants me to use a correlation heatmap, and i found it under reliability analysis, but this plot also looses the p-values for significance. Do you know of a module i can use to make a nice, large correlation heatmap that preserves the p-values?
I do not know of a heat map generator except using ggplot2 in R directly
@@AlexanderSwan Thanks! I think i managed to find a work-around. For anyone wondering, my "solution" was to use the Rj editor module, copy the code Jamovi used to generate the plot into it, and edit the plot dimensions using the gear icon in the code editor. kinda hacky i guess Jamovi would be perfect if it had even a few options to edit plot dimensions.
I used your option and everything works as it should, except for one thing $(user) and $(touser) don't change to the names of who and on who the command is used on. How can I make them change to user names?
I’m not sure - you might need to check the lines of code here to make sure everything is in correct
@@AlexanderSwan i already fixed it
can you do this for a multiple logistic regression?
A good question, but it’s not quite the same, unfortunately
I have been picking my brain about this and I believe you made an error at the end of the video. It seems that JASP ANCOVA graphs don't adjust and basically only show the ANOVA graph. On your exemple both high and low dose have the same mean which shows on the graph but the marginal means are different so if the graph was actually showing the ANCOVA results with the marginal means, the high dose dot would be higher than the low dose, which it isn't. I tried several times on my data and no matter if you add or remove covariates you always end-up with the exact same graph which is quite frustrating. Or am I missing something ?
That seems like it might be a bug with the module on JASP. If I made an error, that’s my bad, I probably didn’t look too closely as I was going through the tutorial. I always recommend making your own graphs in Excel!
Im late but where's lecture 1 ? Pls reply
There isn’t one. This was during the first part of Covid isolation, which happened mid-semester
How do we interpret results tho
That’d be in another video made by someone else. I do minimal interpretation, rather here I just show users how to use the module.
Helped me with last minute feedback to do a correlation from my dissertation defense. Very easy to understand. Love the detail and explanations. Thank you. Hopefully, I will never need it again. Alas, I could have used or found your tutorials over the past year of SPSS stress as I am bio statistically challenged. So if I can suggest more needed on what the correlations actually mean in interpretation in addition to positive and negative.
they don't have the option for bivariate correlation :< will it okay to just use regression?
Bivariate just means two variables, one x and one y. All correlations are bivariate, and a bivariate regression is the simplest form of regression.
@AlexanderSwan oh okay! i misunderstand it. but actually, what i meant with the option that jasp don't offer is the correlation analysis between nominal and scale data. In spss, they were able to make a correlation analysis table for all types of variables i have from my experiment. I don't get it, though, like how SPSS were able to make analysis with the nominal values.
Hi, I'm currently trying to do an assignment where we have to test the hypothesis "Men have higher starting salaries than women, even after the effects of education and work experience are controlled for" and I was wondering how you would do it in Jamovi - would education and work experience be covariates? And if so how do you then read the table to see the relationship?
Yes, you’d put all your predictors into the regression equation and then look at your coefficients. If there’s a gender difference even with those other two variables in the equation, you’ve controlled for them and still have a significant relationship with gender and salary.
Hypothesis 6 in this assignment is tough hey haha
You are a life saver! I have an exam tomorrow
Thanks! If I wanted to look at the effect of IV on DV whilst controlling for variables such as age/height etc, would it be the same thing? Or would it have to be reported differently?
MR is for continuous variables, typically. If you have a categorical IV, you may want to do an ANCOVA. It’s effectively the same thing, math wise, so it just depends on your variables and how you set them up
