When is quota sampling the sensible choice in a design?
Questions from this subtopic
Each one with the model answer underneath.
- 1
What part does a sampling frame play in a research design?
Model answer
It is the list of the research population from which the sample is drawn, and it fixes who can possibly be selected.
- 2
Why is a sampling frame necessary for random sampling?
Model answer
Every member must have a known and equal chance of selection, which is impossible unless they all appear on a list.
- 3
Give two sampling frames a sociologist might realistically use.
Model answer
A school roll and the electoral register are both used, since each lists a defined population in a form that can be sampled.
- 4
Justify the choice of stratified random sampling for a study within a school.
Model answer
Dividing the roll by year group and sex and then sampling at random within each category ensures the sample mirrors the school's composition rather than leaving it to chance.
- 5
When is quota sampling the sensible choice in a design?
Model answer
When no sampling frame exists but the composition of the population is known, so interviewers can be sent to fill set numbers in each category.
- 6
Justify the choice of snowball sampling for a study of drug users.
Model answer
There is no list of a hidden and illegal population, so one contact introducing others is often the only realistic way to reach enough participants.
