I would like to thank God for you. I had looked at several people trying to explain this and could not understand. You were very clear and concise. When you opened up and said this is rather easy, I felt better, because I was about to give up. I thank God for you today Mr. Grange.

Thanks for the vid Jim! Gradated from Keele this summer and I'm currently doing an MRes in psychological resaerch methods at NTU. We're required to do our maths in R here, which is a bit of a jump from JASP at Keele. But I honestly believe that R is much better taught at undergrad level to better prepare for more advanced stats/the job market more generally!

@JimGrange. 3 ай бұрын

Great to hear you're doing an MRes! We discussed at length introducing R at undergraduate level but many people felt it may be a stretch too far initially (both for students and staff!). Glad you are now learning it, though - it will be a great benefit!

So based on the data used, which type is better 1, 2 or 3?

@JimGrange. 4 ай бұрын

There is no "best", here. It depends whether your data (for each condition) come from the same participants or from different participants.

@JimGrange. 3 ай бұрын

There isn't really a "better", as it all depends on your data (i.e., if the values for each condition come from the same people or different people), that is whether your study is repeated measures or independent measures

What if I had two columns of consumer age and another row of the purchase amount, and I wanted to see if there was a correlation between the two, which t-test would I use

@JimGrange. 7 ай бұрын

You would use the =CORREL(range1, range2) function, where range1 is your ages and range2 is your purchase amount. This returns a pearson's r value (between -1 and 1)

@JimGrange. Thanks for that Jim, also how would I go about getting a sample of age ranges from my mass of data so I can do another T-test ? I can't seem to find the answer online

Working on my data analysis now and I already calculated the mean for 2 groups I want to compare but excel tells me I can't just select the calculated mean. So we can only select a list of values from which it will calculate the mean?

@JimGrange. 9 ай бұрын

Correct - You cannot do a t-test just between two mean values. You need the individual data points

Does the same explanation apply to a moderated regression analysis ? Let's say we get all coefficients as significant / moderator is dummy coded 1 for women and 0 for men. If we have a significant negative coefficient for the interaction term, we could say there is a decrease in Y as X increases, but this decrease is stronger for the women's group? How can we better explain the interaction effect when reporting results in a journal? The effect of X on Y is stronger in women? Do we report the difference in numbers? Could you provide an example of how to formally report a moderated regression with a dummy variable?

@JimGrange. 9 ай бұрын

Yes, a moderated regression is the same as an interaction. ANOVA is basically regression in disguise.

@cupcaketv5673 11 ай бұрын

Thank you so much for this! Just one thing regarding the interaction effect. When I saw a few graphs showing two variables that cross each other while both variables had the same level of gradient, I at first thought there was no interaction effect. Since yes, one variable rises while the other one falls, but both had the same level of gradient. But there is still an interaction effect, as I found out. So I personally find it easier to memorize that there's always an interaction effect as long as the two variables aren't parallel.
