Statistics

Question 1

Which type of ANOVA is used for a BETWEEN PARTICIPANTS design?

Answer 1

Independent ANOVA

remember the participants are independent of each other

Question 2

Which type of ANOVA is used for a WITHIN PARTICIPANT design?

Answer 2

Repeated measures ANOVA

Remember they repeat the conditions

Question 3

ANOVAs determine where the variation in data comes from using the F-ratio.

If F < 1 what does this mean?

Answer 3

Unsystematic variance outweighs systematic variance

Test will NEVER be significant

Question 4

ANOVAs determine where the variation in data comes from using the F-ratio.

If F > 1 what does this mean?

Answer 4

Systematic variance outweighs the unsystematic variance.

The larger the ratio (or difference) the more likely that the test WILL be significant

Question 5

Why is a repeated-measures ANOVA more powerful than an independent ANOVA?

Answer 5

Because a within participants design removes error variance/unsystematic variance which is due to individual differences.
