Q

What are the 2 weaknesses for a independant group experimental design?

A

No control of pps variables and more pps neeed

17
Q

What is matched pairs experimental design?

A

Where each pp is matched and variables considered to be relevant to the investigation with another pp

18
Q

What are the 2 strengths for a match pairs experimental design?

A

No order effects, reduced demand characteristics, and control of pp variables

19
Q

What are the 2 weaknesses of a matched Pairs experimental design?

A

Matching pairs of pps may be time-consuming and difficult and large number of pps needed to achieve matching

20
Q

What is naturalistic observation?

A

Where an individual watches and records natural occurring behaviour

21
Q

What is a controlled observation?

A

Where an individual watches and records behaviour where the researcher tries to control certain variables

22
Q

What are the strengths for a naturalistic observation?

A

High ecological validity and no demand characteristics
