Strength: Easily comparable whilst retaining control. Weakness: No reason as to why they put their answer

2 of 19

Describe a strength and weakness of open questions

Strength: No restriction with answer-detailed and rich data. Weakness: Difficult to compare and analyse data

3 of 19

Describe a strength and weakness of closed questions

Strength: Easy to compare and analyse data. Weakness: May miss out on data because it falls outside the allowed responses

4 of 19

Know what is meant by reliability

Repeat and get the same/similar results-consistency

5 of 19

Know how to test a self-report for reliability

Split-half/Test Re-test (same test again at a later date)

6 of 19

Know what is meant by validity

If it measures what it claims/sets out to measure

7 of 19

11 of 19

Identify two strengths and two weaknesses of random sampling

Strengths: Often in large numbers and provides the best chance of an unbiased representative sample of a target population. Weaknesses: The larger the population, the more difficult it is to sample randomly and becomes more impractial

Describe self-selected sampling

Consists of those individuals who have conciously or unconciously determined their own involvement in a study. Eg Volunteers for studies/passers by for field studies

13 of 19

Identify two strengths and two weaknesses of self-selected sampling

Strengths:1. Relatively convenient, and if made on the basis of informed consent, ethical. 2.The choice is not biased by the researcher. Weaknesses: 1. Often unrepresentative 2. Volunteers are unlike non-volunteers in many ways.

14 of 19

Describe what is meant by quantitative data

Data that focuses on numbers and frequencies are known as quantitative data.

15 of 19

Outline one strength and one weakness of collecting quantitative data using self-report techniques

Strength:provides information that is easy to analyse statistically and is fairly reliable. Weakness: Criticised for not providing an in depth description.

16 of 19

Describe what is meant by qualitative data

Data that describes meaning and experiences are known as qualitative data

17 of 19

Outline one strength and one weakness of collecting qualitative data using self-report techniques

Strength: Often high in validity. Provide a more in depth and rich description. Weakness: Not that reliable

18 of 19
