Flashcards in Key terms - quick test Deck (12):
1

Independent variable

Variables that are manipulated to see if it will cause a change to the dependent variable

2

Dependent variable

Variables that are measured in an experiment

3

Confounding variable

Variables that need to be controlled as they could affect the dependent variable, even though the experimenter does not want them to

4

Control group

A group of experiment participants that are not exposed to the independent variable

5

Order effects

The effects that confounding variables have on results

6

Demand characteristics

Behaviours exhibited by participants in order to please the experimenter

7

Repeated measures design

Participant tested on all the conditions of the experiment and then their scores are compared with one another's

8

Independent measures design

Participants exposed to one condition and then their scores are compared to other participant's scores who were exposed to the other condition

9

Matched pairs design

Participants in one condition are matched with a participant in another condition based on particular characteristics (e.g. a measured level of aggression)

10

Counter balancing

The way experimenters control order effects - they change the order of participation between 2 groups

11

Ecological validity

Likeness of an experiment to a real life situation

12

Two tailed hypothesis

A hypothesis that predicts there will be a difference but that it could go either way
