Post-paper 1: your comment about picking the weaker data test if both are present (e.g. ordinal and interval) SAVED ME deciding between spearman's rho and pearson's r in paper 1 BLESS YOU GALBRAITH 🤩🤩🤩
Damn, I was thinking abiut watching this video before the exam, but did not get to it. I literally put Spearmans Rho test for that question, crossed it out and put Pearson's lol. But yout other video's are brilliant, helped me a lot to prepare for paper 1. Your breakdown and dicussion for predictions was great, that was very helpful, so thank you a lot.
Ah that's always the way isn't it. I'm sure you'll still get some marks if there was explaining to do. Thanks for your kind words. I'm glad that the channel has helped you out 👍 -G
I think Pearson is right because the question told us the data was interval, unfortunately I didn’t real the full question so I crossed out Pearson and changes it to chi squared😭😭
Yeah that probably could have been clearer! It's because I didn't show the full stem in the video. They were looking at whether doing team sports (left column) made you happier than doing individual exercise (right column), so we needed to see if the scores had improved from right to left. Look out for that sort of thing in the paper :) -G
thank u! this was really helpful. i was just wondering do u need to know about the tests being parametric or not? and is there a way to know which is which, if u need to know?
You're welcome, and I'm glad! The specification does not mention 'parametric', so no, you don't. Parametric tests are used when certain criteria are met: when data fits a normal distribution, and when the standard deviations are equal. The parametric tests are the interval level ones, if you're interested. -G

Love it. Charizard is the goat.
@@GalbraithDoesPsych fr gonna smash this paper
Get it done :)

@@GalbraithDoesPsych That paper was so good, thank you so much. When will you be making vids for paper 3?
I'm on it! Making content over the next few days!
Glad it went well for you 👍

What was the answer
@@i.o.creates I put spearman's rho
@@i.o.createsIt was Spearmans
Hey, I appreciate it 🙏 good job you remembered it haha.
If it was correlation and the co-variables were ordinal and interval, then yeah Spearman's.

could this kind of question come up again? or did i miss my chance lol

same here i'm so gutted i didn't watch this vid before paper 1

ur so underrated omg😭 I luv ur vids sm they help a lot !!
Very kind. I actually can't believe how many people are commenting and how nice everyone has been.

omg the absolute legend!! watching this properly in a second youre amazing
Aw shucks.

Also, for the sign test, why are you going right to left instead of left to right?
Yeah that probably could have been clearer! It's because I didn't show the full stem in the video.

Outside the sign test, is there any other context in which the N value would be less than the actual amount of participants in the study?
Not unless you're explicitly told that an outlier is being excluded, for example. I can't remember if I've ever even seen that though.
