Question 4

Random allocation

Answer 4

An attempt to control for participant variables in an independent group design which ensures that each participant has the same chance of being in one condition than the other.

Question 5

Counterbalancing

Answer 5

An attempt to control the effects of repeated measures design, half the participants do the condition in one order and the other half in the opposite order; to avoid order effects

Question 6
