16
Q

Experimental condition

A

Group of participants are exposed to the IV

17
Q

Control condition

A

IV is not treated/ manipulated.

18
Q

Independent measures design

A

Participants take part it only one experimental condition

19
Q

Repeated measures design

A

Participants take part in both experimental and control conditions

20
Q

Matched pairs design

A

Independent groups design where the experimental and control. Participants are deliberately similar e.g. balance between gender

21
Q

Counter balancing

A

Used to deal with order effect when using a repeated measures design. Participants complete conditions in opposite orders

22
Q

What is opportunity sampling?

A

Participants are chosen by their convenience to the researcher, they know no details in advance.

23
Q

What is systematic sampling?

A

Every nth person is selected by the researcher.

24
Q

What is stratified sampling?

A

Target group is divided into sub groups. Participants are selected randomly from each sub group.

25
Q

What is quota sampling?

A

Participants decided into sub groups. Participants from each sub group is selected by the convenience to the researcher.

26
Q

What is self selected sampling?

A

When the participants volunteer them selves by responding the the psychologists advertising

27
Q

What is snowball sampling

A

Participants are initially recruited by the psychologist and recruit further people they know.

28
Q

Event sampling

A

Participants are observed by researcher. Specific behaviour is recorded each time it occurs to create a total score.

29
Q

Time sampling

A

Psychologist records behaviour at specific time intervals and then creates an average score for each participant.

30
Q

Privacy

Refers to a zone of inaccessibility to the mind and body and trust that it will not be invaded

31
Q

Confidentiality

A

The communication of information from one person the another and trust that it will be protected
