11. Repeated measures ANOVA Flashcards
What is systematic variance? (Repeated ANOVA methods 2)
the effects from manipulation of the experiment
What is random variation? (Repeated ANOVA methods 2)
Performance changing due to natural factors such as individual differences
What is the correct word for conditions when describing an ANOVA? (Repeated ANOVA methods 2)
Conditions
How do you work out the total DOF? (Repeated ANOVA methods 2)
Number of scores minus 1
How do you work out the between groups DOF? (Repeated ANOVA methods 2)
the number of groups minus 1
How do you work out the within groups DOF? (Repeated ANOVA methods 2)
The number of scores in group 1 - 1, added to the number of scores in group 2 - 1 etc
When completing an ANOVA, what DOF do you recall?(Repeated ANOVA methods 2)
Within groups and between groups
What is the total sum of squares? (Repeated ANOVA methods 2)
it reflects the total amount of variation amongst all the scores
What does between treatment sum of squares measure? (Repeated ANOVA methods 2)
The amount of systematic variation between the subjects
What does the within treatment sum of squares measure? (Repeated ANOVA methods 2)
The amount of unsystematic variation inside each treatment
How do you work out within treatment sum of squares? (Repeated ANOVA methods 2)
Add the sum of squares for each group
How do you work out the between subjects sum of squares? (Repeated ANOVA methods 2)
Work out the personal mean for each participant
What is the error sum of squares? (Repeated ANOVA methods 2)
A measure of the amount of unsystematic variation within each subjects set of scores
What is he equation for error sum of squares? (Repeated ANOVA methods 2)
ESS = WTSS - BTSS
What is the equation for the critical value? (Repeated ANOVA methods 2)
CV = MS between / MS error
