experimental design

Question 1

experimental design

Answer 1

the different ways in which participants can be organised in relation to the experimental conditions

Question 2

independent groups design

Answer 2

participants allocated to different groups where each group represents one experimental condition

two separate groups involved, each group does one of the conditions of the experiment

Question 3

repeated measures

Answer 3

all participants take part in all conditions of the experiment

Question 4

matched pairs design

Answer 4

pairs of participants are first matched on some variables that may affect the dependent variable

then one member of the pair is assigned to condition A and the other to condition B

attempt to control the confounding variable of participant variables

Question 5

random allocation

Answer 5

an attempt to control for participant variables in an independent groups design which ensures that each participant has the same chance of being in one condition as any other

Question 6

counterbalancing

Answer 6

an attempt to control for the effects of order in a repeated measures design

half the participants experience the conditions in one order, and the other half in the opposite order
