Key Concepts and Theories of Research
Representativeness and the sample
- 3 things to know
- Component 2
Overview
Why a large sample can still misrepresent: biased frames, self-selection and volunteers, what a case study can and cannot support, and when a small random sample beats a big convenient one.
What you need to know
Answer each one before you reveal it.
What does representativeness mean?
On which characteristics should a sample be representative?
Questions from this subtopic
Each one with the model answer underneath.
- 1
What does representativeness mean?
Model answer
Representativeness is the extent to which a sample reflects the characteristics of the population it came from. A representative sample is a miniature of the whole.
- 2
On which characteristics should a sample be representative?
Model answer
A sample should match the population on the characteristics relevant to the topic, such as age, sex, class or region. Irrelevant characteristics do not matter.
- 3
Why is representativeness a property of the sample rather than the method?
Model answer
Any method can be applied to a good sample or a poor one. Interviewing is neither representative nor unrepresentative in itself.
- 4
How is a sample's representativeness checked?
Model answer
A sample's composition is compared with census or other population figures. Divergence shows which groups are over- or under-represented.
- 5
What is weighting?
Model answer
A weight adjusts the influence of each case so that the sample's profile matches the population. Under-represented groups are made to count for more.
- 6
Give one limitation of weighting.
Model answer
Weighting corrects the proportions but not the fact that few of that group were interviewed. A handful of cases is stretched to speak for many.
