Q

Give 2 strengths of naturalistic observations.

A
  • normal environment = representative behaviour

21
Q

Give 2 weaknesses of naturalistic observations.

A
  • Extraneous variables = not controlled

* validity compromised if observer suspected

22
Q

Give 2 strengths of controlled observations.

A

25
Q

Give 2 weaknesses of a structured observation.

A
  • if not operationalised properly wrong recordings = less valid

26
Q

Give 2 strengths of an unstructured observation.

A
  • produces quantitative data

* no categories - any relevant behaviour recorded

27
Q

Give 2 weaknesses of an unstructured observation.

A
  • may miss behaviours - looking at everything

* inconsistent/subjective

28
Q

Give a strength of an opportunity sample.

A

• quick & easy

29
Q

Give a weakness of an opportunity sample.

31
Q

Give a weakness of a self- selected sample.

32
Q

Give a strength of a snowball sample.

A

• easy as only find first few P’s

33
Q

Give a weakness of a snowball sample.

A

• non- representative = similar characteristics

34
Q

Give a strength of a random sample.

A

• representative

35
Q

36
Q

Give a strength of a stratified sample.

A

• representative

37
Q

Give a weakness of a stratified sample.

• difficult - all subgroups must be known

38
Q

Give 2 strengths of quantitative data.

A
  • collected using objective measures

* can be analysed using inferential statistics

39
Q

Give 2 weaknesses of quantitative data.

A

• limits P’s response

40
Q

Give 2 strengths of qualitative data.

A
  • highly valid as P’s can express themselves

* less likely key/rare observations lost by simplifying data

41
Q

Give 2 weaknesses of qualitative data.

A
  • data from individual = hard to generalise

* interpretation may be biased = invalid

42

Give 2 strengths of questionnaires.

43
Q

Give 2 weaknesses of questionnaires.

A

44
Q

Give 2 strengths of interviews.

A
  • structured = easy to analyse

* semi-structured & unstructured = specific & detailed info

45
Q

Give 2 weaknesses of interviews.

A
  • structured = limited by fixed questions

* investigator bias = leading questions alter ways asked

46
Q

Give 2 strengths of both questionnaires and interviews.

A
  • structured questionnaire & interviews = repeatable

* produce quantitative and qualitative data

47
Q

Give 2 weakness of both questionnaires and interviews.

A
  • not everyone can be bothered so P may not be representative
  • P affected by biases like social desirability, leading questions, etc
48
Q

Give 2 strengths of rating scales.

A

* quantitative = easy to analyse

49
Q

Give 2 weaknesses of rating scales.
