Questions from this subtopic
Each one with the model answer underneath.
- 1
What is snowball sampling?
Model answer
A method in which initial contacts introduce the researcher to further participants, who introduce others in turn.
- 2
Why is snowball sampling often the only option for studying hidden groups?
Model answer
Because such groups appear on no sampling frame, so members can only be reached through people who already know them.
- 3
Give an example of a group for which snowball sampling would be appropriate.
Model answer
People involved in illegal drug use, who would not identify themselves to a researcher approaching them cold.
- 4
Explain how trust is transferred in snowball sampling.
Model answer
An existing participant vouches for the researcher, so the next person is willing to take part on the strength of that recommendation.
- 5
Give the main weakness of a snowball sample.
Model answer
Participants recruit people like themselves, so the sample reflects one network rather than the whole hidden population.
- 6
Why can a snowball sample never be shown to be representative?
Model answer
The size and composition of the hidden population are unknown, so there is nothing to compare the sample against.
