Q

do you want the inverse efficiency score to be high, why

A

no you want it to be a low scores it shows that external factors are being eliminated

Q

how to compute a mixed subjects two-way ANOVA into SPSS

A

analyse –> general linear model –> repeated measures –> put in appropriate within-subjects and between-subjects in the dialogue boxes –> also create a profile plot and selected display means

Q

how do you write up a two-way mixed ANOVA

A

say if the findings are significant or non significant of ________ (first variable) F (small df value, big df value) = F value, P= P value and _______ (second variable) F(small df value, big df value) = F value, P = P value

16
Q

how do you report the interaction of a two-way mixed ANOVA within-subjects

A

these should be interpreted in light of the statistically significant interaction, F (small df value, big df value) = F value, p = P value

17
Q

when looking at the lines on a profile plot of a two-way ANOVA, if there was to interaction, how would the lines look

A

they would be parallel to each other

18
Q

what is a simple effect in a two-way ANOVA

A

a way you can asses the interaction between two variables rather than all of them

19
Q

what is one way of calculating a simple effect of a two-way ANOVA

A

t-test

20
Q

how do you report a simple effect test

A

simple effect analysis revealed that disruption resulting from _____ was presented for the _____ (report a t-test) t= t value, P= p value , but not the ______ t= t value, p=.303

21
Q

how do you do a two-way within subjects two-way ANOVA on SPSS

A

analyse –> general linear model –> repeated measures –> specify the within subjects, don’t specific any between-subjects

22
Q

how do you do a two-way between-subjects ANOVA on SPSS

A

analyse –>general linear model –>univariate –> specify DV both between subjects factors are moved to the fixed factors list
