Experimental design

Repeated measures + evaluation p and n

all participants complete all conditions.

+Doesn’t need may participants

-Order effects e.g. fatigue, practice

To deal with limitation, you can counter balance which you can do the conditions in a different orders, ABBA

Independent groups + evaluation

participants are placed into groups then tested on one independent variable

+No order of effects

-Needs a lot of participants

-No control of participant variables —> to deal with the limitations- participants can be randomly allocated to distribute participant variables

Matched Pairs + evaluation

two participants are matched by key characteristics then placed into different groups

+No order of effects

-It is time consuming. To deal with this limitation—> conduct a pilot study to decide the key characteristics you want to focus on

experimental design

structure of the study to do with participants.
