Reliability is the extent to which a method can be repeated by another researcher and produce consistent results.

What makes a sample representative?

A sample is representative when it is a typical cross-section of the research population, matching it in the characteristics that matter to the study.

A structured questionnaire is repeated and produces almost identical answers, but many respondents had misunderstood a key term. Which concept is high, and which is undermined?

Reliability is high because the results are consistent, but validity is undermined because the answers do not reflect what the researcher intended to measure.

Why are representativeness and generalisability not the same thing?

Representativeness is a property of the sample itself, while generalisability is the claim the researcher can then make about the wider population; a sample must be representative before findings can be generalised.

Questions from this subtopic

Each one with the model answer underneath.

1
Define reliability.
Model answer
Reliability is the extent to which a method can be repeated by another researcher and produce consistent results.
2
What makes a sample representative?
Model answer
A sample is representative when it is a typical cross-section of the research population, matching it in the characteristics that matter to the study.
3
What does generalisability mean?
Model answer
Generalisability is the extent to which findings from the sample can legitimately be applied to the wider research population.
4
A structured questionnaire is repeated and produces almost identical answers, but many respondents had misunderstood a key term. Which concept is high, and which is undermined?
Model answer
Reliability is high because the results are consistent, but validity is undermined because the answers do not reflect what the researcher intended to measure.
5
Why are representativeness and generalisability not the same thing?
Model answer
Representativeness is a property of the sample itself, while generalisability is the claim the researcher can then make about the wider population; a sample must be representative before findings can be generalised.
6
How does a sociologist's theoretical position guide their research?
Model answer
Theory shapes the topic thought worth studying, the aims or hypothesis set, the method selected, the type of data collected and the way the findings are interpreted.
