Quota sampling
- 3 things to know
- AS Unit 2 and A2 Unit 4
Overview
Recall questions on how quotas are filled, why no sampling frame is needed, who gets missed on the street, the bias interviewers introduce, and when the results still hold up.
What you need to know
Answer each one before you reveal it.
Give one reason quota sampling does not require a sampling frame.
Explain the main weakness of quota sampling.
Questions from this subtopic
Each one with the model answer underneath.
- 1
What is quota sampling?
Model answer
A method in which interviewers are told how many people of each category to interview and choose those people themselves.
- 2
How does quota sampling differ from stratified random sampling?
Model answer
Both fix the proportions of each category, but quota sampling lets the interviewer pick the individuals rather than selecting them at random.
- 3
Give one reason quota sampling does not require a sampling frame.
Model answer
Respondents are recruited on the spot until each quota is filled, so no list of the population is needed.
- 4
State two practical advantages of quota sampling.
Model answer
It is quick and cheap, and it can be used where no sampling frame exists.
- 5
Explain the main weakness of quota sampling.
Model answer
Interviewers choose who to approach, so their preferences bias the sample and no claim about probability can be made.
- 6
Why is quota sampling described as a non-probability method?
Model answer
Because the chance of any individual being selected is unknown, so statistical confidence cannot be calculated.
