that table is so good, I'm so happy i found this account, was actually near tears when my psych teacher said to make sure I knew stats tests before paper 1, which im taking tomorrow... 🙇🙇🙇
OMG thank you, ive always failed to understand inferential statistics and the tests, ive got my paper two tommorow and youve just relieved so much stress
comments 34 on 3-9-2022. In 1996 I was handed a book of these test. It was pre degree. My response was: "Oh I see, I'm supposed to believe all this". I carried one out to get a certificate. Take a look at the reality.
For the final exam question, couldn’t one argue that it is a test of correlation since they may be testing the correlation between time (years over decades) and amount of people who smoke?
@@smcartledge2723 Thankyou so much for replying. Its the context of the example given in this video. I used screenshots and examples from the video in a tutoring session but was at a loss to explain why before-after isnt ordinal...
Ah right. So before and after data can technically be all three of them, it always depends on what you’re actually measuring. So in my example I was looking at whether patients improved in terms of their symptoms before and after receiving treatment. But I wasn’t interested in how much they had improved, I was only interested in whether they had improved or not. Which means that they are in categories. They either have improved or they haven’t. However, if I was rating their improvement in some way, and then ordering them for example, then you would be right, it would be ordinal. Does that make sense?
I am currently teaching this to Year 13s as a non-specialist, your videos have been incredibly helpful, thank you. Just one question: Why choose Spearman's over Pearson's if the data is interval? Also, I found an example looking at foot size and number of oranges peeled in 5 minutes. My class were asking why Spearman and not Pearson and I couldn't convince them successfully!!
Hi, thanks for your feedback. Where did you find the question? Based on that information it sounds like it should have been Pearson's, as the amount of oranges peeled sounds like interval data. Is there anymore information to the question?
I'm assuming you're referring to Phoebe's experiment with the heat experiment. It's Ordinal data because Phoebe is assigning a natural coherent rating scale of 0-10 based on an increase in temperature of 5*C. The rating scale is the form of measurement, not the temperature. Therefore it cannot be interval data.
this is so helpful! also, for the exam do we have to learn to convert between the levels of measurement ie interval to ordinal because i saw that mentioned on another video?
hi this umis useful. But why is anoba, f test, z test, and kruskal wallis test not included. When to use this. i got a test for tomorrow. please answer
10:40 could someone please explain why this is unrelated ? how is it not repeated measures if everyone is experiencing the same experimental condition? Thanks
Because nothing is being repeated. Think of every individual questionnaire as an independent group. Every participant is completing one questionnaire and so is only experiencing one level of IV. It would be a repeated measures, if they all took the questionnaire again and the answers were then compared to see if any change had occurred. I hope that helps.
You are so much better than Psychboost man
1000%
I couldn't learn with Psycho 😭😭😭 I wish I had him before in Th first year
@@faithfuljohn2001 for real
got a paper 2 mock tomorrow, and this has just helped me more than any revision or lesson ive ever done on stats test. Thank you!
i hope it went well !
good luck on your tuesday exam
This is excellent. I wish you every success with the channel!
Thank you
You’re my favourite research methods teacher, thank you!

@@gabriellevannoordwyk7821 you too!! good luck 💪🏼💪🏼
it didnt even come up in paper 1 but defo coming up in paper 2 and 3
OMG thank you, ive always failed to understand inferential statistics and the tests, ive got my paper two tommorow and youve just relieved so much stress
this is by far the best video that explains everything you need to know in a very straight forward approach to help you learn!
Amazing job. Thank you so much. You are a great teacher
Thank you for your comment.
thankss, i couldnt understand it when my teacher taught it but this is a really good explanation
for psychology a level research methods, i always come back to this video. the simplest explanation around. thank you
I LOVE YOU
Thank you for this! This is very helpful and taught me better than my teacher did!
Thank you so much for this video!! so helpful :)
Thank you for the help.THIS REALLY HELPED!!!!!!!!!

Sorry- quick but crucial question. Why is "before" and "after" data classed as nominal? I would've thought it'd be ordinal
Hi there.
What is the context - before and after data could technically be any of them.
Thanks

The tests in the video are the only ones you need for a-level psychology.
There are other tests but you don’t need them.

@@smcartledge2723 I think I understand now, there is only one experimental condition so it's not repeated measures. Thank you for explaining😊
Thank you sm for asking this I was so confused but scared he won’t reply since he made this video over a year ago 😭
I'm in love with you
