-the subjects are organised into groups is called the design of the experiment
Outline independent groups design
-Where different participants take part in each experimental condition
define matched pairs
-Where participants take part in only one experimental condition, but they are recruited specifically to be similar in relevant characteristics (e.g. intelligence, gender, age) to ‘matched’ participants in the other condition(s)
define repeated measures
-Where the same participants are allocated to all groups (i.e. take part in all conditions) of an experiment.
Define counterbalancing
-technique used to deal with order effects when using a repeated measures design.
-With counterbalancing, the participant sample is divided in half, with one half completing the two conditions in one order and the other half completing the conditions in the reverse order
