?
What is Independent Groups design?
When each separate groups of participants experience single separate conditions of an experiment
1 of 10
What is a Repeated Measures design?
When each participants experiences all conditions of an experiment
2 of 10
What is a upside of a Repeated Measures experiment?

3 of 10
