week3. 2-way ANOVA

Question 1

how many independent variables does a two-way ANOVA need to have at least

Answer 1

2

Question 2

are two-way ANOVA’s factorial

Answer 2

yes

Question 3

what does a two-way ANOVA provide with its results

Answer 3

a significance test for each factor (main effect) and the interdependence of the effects of each factor (the interaction)

Question 4

does a two-way ANOVA show the relationship between two independent variables swell as their effect on the dependent variable

Answer 4

yes

Question 5

what is inverse efficiency

Answer 5

it is the calculation of response time and accuracy

Question 6

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

Answer 6

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

Question 7

what value provides a general measure of performance

Answer 7

the inverse efficiency score

Question 8

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

Answer 8

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

Question 9

how many summary tables do poi need to look at for a two-way ANOVA

Answer 9

two

Question 10

what row of the two-way ANOVA within-subjects table do you need to report in a mixed-subjects

Answer 10

the sphericity assumed

Question 11

what does the sphericity assumed row on a two-way within-subjects ANOVA table show in a mixed-subjects

Answer 11

the main effect

Question 12

what row of a two-way within-subjects ANOVA table shows you the main effect in a mixed-subjects

Answer 12

the sphericity assumed

Question 13

what row should you look at on a two-way between-subjects table in a mixed subjects

Answer 13

the second row, not intercept

Question 14

how do you write up a two-way mixed ANOVA

Answer 14

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

Question 15

what does the second row tell you in a mixed two-way ANOVA within-subjects table

Answer 15

the interaction of the variables

Question 16

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

Answer 16

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

Question 17

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

Answer 17

they would be parallel to each other

Question 18

what is a simple effect in a two-way ANOVA

Answer 18

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

Question 19

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

Answer 19

t-test

Question 20

how do you report a simple effect test

Answer 20

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

Question 21

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

Answer 21

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

Question 22

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

Answer 22

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