Thanks that's amazing! I'm actually in Germany writing my master thesis and I'm a bit lost with the G*Power Program! so thank you so much :)

Dr Miranda, thanks a ton for your explanations. However, it is my opinion that the publishers should have included the equations by which they derive their results. Although I am a math nerd (aced Calc/calc2 as an undergrad and 2terms of advanced quantitative methodology at the 8000level), I am a psychologist (PhD forensic psych, almost finished). For my CH3 (of The Big D, of course), I’m pretty sure it is insufficient for candidates to merely cite GPower. They have to be able to explain how they got there. It is analogous to using a graphing calculator for a calc exam - ya gotta know the theory, application and show the work; they cannot merely use the shortcut software and reference it, in this case. ‘Just insert into your dissertation’ was a little misleading. If they cannot show how they came to the sample size via their power study (perform the hand calculations; yes, depending on the statistical analysis used, there may be as many as 5-7complex algebraic linear equations to solve to get to that projected sample size), that’s a problem. That’s like saying, ‘well, I just let Joe Blow do that for me bc he’s an expert’. That’s a no-go. But hey, I appreciate your explanation of the use of GPower to project the minimum n. Thank you.

hi, currently I'm conducting a research and want to use gpower. I want to ask, can I use gpower to get the sample size eventho I already know my population is 18,000 ? I would appreciate if you can enlighten me regarding this. Thank you

I just wanted to reconfirm. For t-tests (Linear multiple regression, fixed model, and single regression coefficient, the number of predictors is the number of independent variables? I am really new to this so i would appreciate the help

Sir, I have a target population of 300, what minimum number of individual I need to survey in that target population. As I am preparing to begin my writing my dissertation, I safely assumed 300 is a good number of individuals to ask to participate in my survey. How do I get G*Power to tell me the minimum number I need to interview.

Hi thank you so much for the video, i'm using g power for my MA thesis, but i'm a bit lost: i want to use linear multiple regression to test the which variable influences most on the user's willingness to use the product. And i have 8 variables, what should i put in the 'number of predictors'?

hi, Thanks for the video. Could you please tell me what denotes "number of groups"?. My model has four independent variables, one mediating variable, one dependent variable and three moderator variables. Whether the number of predictors include mediator and moderator variable?

Hi! Our study has a mediating variable and 1 iv and 1 dv. How are we going to use gpower to find its sample size?
@pugilemoltobene3708

A mediating variable as in you are looking at different levels of the IV? Sounds like a MANOVA - that’s an F type test.
