For question 2, C is the right answer, not D. For question 3 D is the right answer, not A.
thanks!

For the tutorial questions, for question 1 C is not the right answer, D is. And for question 4 it‘s the same, C is not the right answer but D is.
be careful here, the null hypothesis of the Mauchly's sphericity test is that there is sphericity, which is why we don't want to reject the null hypothesis
isn't that what it says in the table? :)
Does anyone have all the answers to the course manual multiple choice questions?

Hey dear Anonymous! Will you provide the same type of summary for the other modules? I would appreciate it a lot! Thanks :)

Hey! Have you got the outputs/notes from the other RLectures please? I would be eternally grateful (since I want to graduate this year..) Thanks!
i do! ill upload them as soon as i’m done with them 😉
Thank you so much!
Hey guys! I hate to ask this but is anyone interested in copying the PPP book from Vince and putting it in here? I am really struggling.

Thank you so much for sharing this! Do you have, by any chance, the previous ones?
I will do them one by one soon, this is actually the first one I did properly :D
Hey, Does anyone still have their SPSS II practical notes? would be greatly appreciated?
fuck this exam
Can someone tell me how i can calculate the estimated marginal means? I think Nick once mentioned a formula in a PLecture but i cannot find it in my notes
i hope this helps. its under "unweighted". oh and it looks like a 3,75 but its a 5,75
You're a lifesaver, thank you!! :)

Is there an answer key to this exam?
this is not correct: the populations are split into the levels of the BS factor - not the WS factor with the 2 timepoints!
Hey all, I 'm having difficulties understanding when we can say something about just the sample, or about the population as a whole as well. In almost all previous exams, there's a question in the form of 'according to the output, what can we say about the effect of ... on the sample and/or on the population'. I'm inclined to think that we can always only say something about the sample, given that our experiment is just a random sample of a much bigger population, but according to the answer models this is not the case. Could someone help me out in distinguishing these two? E.g. which data in the SPSS output belongs to what, or when will the effect of sample/population not be the same?
Basically, you can ONLY answer questions about the Population based on formal tests (t-tests, F-test etc.). So for example let's assume you have a one-way ANOVA and want to test the effect of 3 treatment groups. Treatment group 1 has a mean of 130, group 2 a mean of 140 and group 3 a mean of 160. The ANOVA then tests if the mean difference that you observe in the SAMPLE, is also the case in the POPULATION! So whenever a questions asks about the SAMPLE -> Look at the results of your actual data (Descriptives, Plots etc.) in the example above, we would answer that there is clearly a mean difference in the Sample (-10 between G1 & G2, -20 between G2&G3, -30 between G1&G3) Whenever asked about POPULATION -> Look at significance of tests. Let's say ANOVA yielded the p-value 0.3 - we'd say that there's no mean difference at population level, as there was no significant result
It makes a lot more sense now, thanks :)

Do you maybe have the answer key for that one?
When H0 is not true, MS within is an unbiased estimator of the error variance only, not MS between :)

what is meant by "L SEP" ? Tia
in what context did you find it?
I think you can ignore it, seems like a pdf problem ..

I would also appreciate it
I just uploaded it, hopefully it's still useful …
Hi! Does anyone know why in the 'formatieve toets' week 5 the answer to question 6 is D?
Does anyone have the answer key of the 2014 version A exam?
Is there maybe anybody who has good notes of the practical lectures and the right SPSS Outputs? I sometimes had problems to follow him. Thanks a lot:)
Could anyone share their answers to the study questions from weeks 2 and 3 ? :-) It would be awesome. Thank you :-)
I don't really get the idea of interaction effects.. "the two profiles are roughly parallel so there is no clear interaction bewteen location and yearthese two parameters"... but I find the profiles look pretty parallel??
parallel = no interaction (the graph in the picure is just slightly non-parallel, so you can still say that there is no (significant) interaction) for non parallel graphs the Field book says: - Non-parallel lines on an interaction graph show up significant interactions. However, this doesn’t mean that non-parallel lines always reflect significant interaction effects: it depends on how nonparallel the lines are. - If the lines on an interaction graph cross then obviously they are not parallel and this can be a dead give-away that you have a possible significant interaction. However, if the lines of the interaction graph cross it isn’t always the case that the interaction is significant.
