hi, if I have to run multiple tests both parametric and non parametric. how do I calculate the sample size? the tests fall under different test families

Hi Alexander , thank you so much for these outstanding videos on jamovi, i want to ask is this the last topic of jamovi

Looking into the new research on fascia and its elements as our 'third nervous system' might be an interesting topic for you to explore in future videos! Thank you for taking the time to create these lectures-they're incredibly insightful and inspiring. I'm planning to enter the field myself and really appreciate the valuable content you're sharing. Cheers!

Thanks, Can I use Confirmatory Factor Analysis for one factor on the undimentional questionnaire? thanks for your answer

Got the clicky buttons

May I ask how to prepare your data? It always comes out with an error whenever I use McDonald's omega

India was a lot advanced in Medicine as Ayurveda which was in practice since 2500 BC. People are now again relying more on Ayurveda which is a holistic approach. Mind Body concept existed even before BC as Ayurveda considers this very strongly. Not only Ayurveda the concept of mind body is an old concept in YOGA.

In the table at the start with the data, the 3 DVs were seemingly measured 11 times in each group, right? So when you conduct the MANOVA, why does it only say "Group"? How do you differentiate between the three groups? Does the MANOVA not give me data comparing Group 1 (and 2, and 3) with DV 1, DV 2, DV 3? Thanks!

Hi, the analysis in the violin plots are slow. I tried to change them. The module is improved more. Check it back when you have time :)

This is so funny to watch thank you. you kept me interested despite being utterly uninterested and solely watching this because I am assigned to statistical treatment against my will :)

Let's say you want to predict job performance (dependent variable) and you have: Block 1: Education level (predictor 1) Block 2: Job experience and conscientiousness (predictors 2 and 3) With hindsight, what they tell in Jamovi website is to add the first predictor (Education) in "Term1" and the second (experience) and third (conscientiousness) together in "Term2". Jamovi will then provide output showing: The model statistics (R²) for Block 1 (education alone). The change in R² (R² change) when Block 2 (experience and conscientiousness) is added. The coefficients for each predictor in each block. I think this video points on multiple regression, or else you could shed light on it regarding my comment. However thank you for your detailed description which is very helpful for students.

Statistics is a night mare for me :) Thank you for making it more easy and understandable for us :)

Sometimes on the unbearably woke end of things - expected from the beta-male, ally persona.

Thank you for this. Is it possible to get a p value for ICC in JASP. Or do you know a way to calculate it by hand with the information provided by JASP?

You talk too much

Can you share the sources for CFI, TLI, and RMSEA cutoffs?

out of date

Hi Prof. Swan, I have a question regarding selecting which MANOVA test. I have 5 DVs (5 factors of personality) and then 3 IVs (culture, gender and type of sport). The research question is to see if culture (multiple levels) has an effect on personality, while gender and type of sport (both two levels) play a moderating effect. Can you point me to which test I should use on G*Power and what should go in each box? Thanks so much!

In the beginning classical PhD joke)

hi, i stumbled upon this vid because apparently my data is non-linear, so i cant perform simple mediation analysis in PROCESS in SPSS. Is it correct if i use GLM mediation model for simple mediation with non-linear data? (i've deleted outlier and transformed my data with log, ln, and square but path a remains non-linear).

May I ask if there is a way to increase the decimal places in the pspp output e.g. say standard deviation in descriptives since it seems to default to two decimal places only?

youre a blessing, 4yrs+ and counting! Tysm

Hello Alex, could you please maybe interprete the relationship between f² (R²) and the calculated sample size? I'm confused by the truth, that if I have a higher R² value, which results in a higher f² too, the total sample size i need to fullfill all the alpha-/(1-beta)-values is getting lower...? what happend, if I have a model with bias, which means, one or two of the independent variables are actually not significant, but can push the R² value higher?? In this case, i might actually need more samples to justify my model, but after the F-tests output parameter, i might only need less than 20 samples... I would really appreciate if you could spend 1 min time for my amateur level question. Thanks in advance! H.

hello! can i have the raw data please, thankyou!

Your videos are so easy to understand. Today I heard about this software and just got your tutorial videos. Very helpful for me. Is jamovi an advanced version of SPSS?

Hello, thank you for the great information about JAR :) I would like to ask, how we can get the linking data? thank you

Next time please explain slowly

How do you move the scatterplot equation and r2 value around?

would you be able to do a video where you have the results data set with an unknown design and work backwards to decipher what sort of test was run then create an apa write up accordingly? many of my statistic assessments have followed this structure, it would be helpful (and appreciated) to see how you would approach such a task

Thank you for the video, however I think you explain to who understand already.

You have an upbeat and engaging delivery of statistics! Such a breath of fresh air! Sincerely, thank-you :)

Can I use nominal variable with dummy code as independent variable?

How do you know if it is significant or not? I have a value of .95

Is there a similar video but for a moderation analysis? Thank you.

saved my ass man, what a great vid!

Thats multiple regression mate, not multivariate

Dr. Swan, I'm an American grad-student in Europe ( struggling in statisitics at the moment) and this series of lectures along with the one you did 4 years ago have been a GODSEND. If you ever look at yourself in the mirror and wonder if it's worth to sacrifice so much of your precious time to do these videos, just close your eyes and remember all of us who are able to fulfill our rites of passage in life thanks to your tutelage. We can't thank you enough..

MedMod does not directly yield B values, but in APA7 we are required to report them. Any suggestions on how to proceed?

I certainly see a lot of potential in this. I have an idea for you. Why not try to use this to predict forex prices and compare real data with it. I think it is a kind of controversial topic right now. FBprophet seems to have potential to become a leading trade indicator. Also, there is very good potential in medicine, supply chain management, business analysis to name a few. Thank you for this. I have started testing it out in some ways

Halo Alex, the video is really good. I would like to ask a question about plotting a moderation graph for SVO. How can I visualize the moderator effect on the independent variable (IV), mediator, and dependent variable (DV) with lines representing low, medium, and high levels?

Hello Dr. Alex. Thank you very much for your tutorial videos, they're helping me a lot in my Ph.D. I do have a question, though. Is it possible to perform a logistic regression using repeated measures from the sampled subjects? Is there a way to account for the random effects of each individual?

Saved me while writing my thesis. Thank you so much for this!

Thank you for keeping updating the content of JASP.❤

Thank youuu ❤️ Paying 18k for uni and I have to come on TH-cam for a video, this is so helpful x

Omg i just wanna say tysm for this! I had a hard time grasping this lesson and finding this is sort of like a blessing 🎉

Thanks!

Thank you for your great videos. One of my friend is a professor and uses JASP to teach. I prefer Jamovi and one of the main points is that Jamovi works much better with R to get a more full experience with the software. Thanks, Fraser Schwalley

I have two waves of data, time 1 measure and time 2 measure. I not only want to determine if there is a mean difference between the two, but are there covariates such as age, BMI, presence of cardiac disease etc. which influence the results? I was told I could do a t-test, but the RM ANOVA would be able to account for the covariates. Do the covariates just reduce the noise, or can they explain the difference?

You made the world a better place! Thanks!
