Lecture 7 - Factorial analysis of variance : Repeated measures.

Question 1

How do you know if its a 2x2 repeated measures

Answer 1

2 factors, 2 levels, 1 dv, the same participants

Question 2

What are post hoc tests following a significant interaction called

Answer 2

simple effect tests - must be bonferroni corrected.

Question 3

What is cohens d

Answer 3

The magnitude of difference between 2 conditions. Which provides an indication of the deviation between the means in standard deviations.

Question 4

How do you calculate cohens d

Answer 4

mean 1- mean2/ mean sd.

Question 5

What is partial eta squared

Answer 5

A global magnitude of the difference between groups or conditions. Provides a measure of how much of the variance is accounted for by the treatment effect.

Question 6

How is partial eta squared calculated

Answer 6

effect/ effect + error

Question 7

What needs to be changed when finding the descriptive stats?

Answer 7

must click *dependents together

Question 8

How to conduct a repeated measures anova in spss

Answer 8

1. Analyse- general linear model - repeated measures.
2. Name the factors
   i.e. Factor 1 has 2 levels, factor 2 has 2 levels
   Factor 1= drink (the first number)
   factor 2 = drug (the second number)
   1,1 - alcohol, placebo
   1,2- alcohol, coke
   2,1- water, placebo
   2,2 water, coke
