- takes only a finite number of values
- data which is places in an order or scale but each number will convey special info
3. What is Quota Sampling? (non-probability)
- non-probability equivalent of stratified sampling - characteristics need to be identified and their proportions BUT Convenience or judgement sampling is then used to select the required number of subjects.
- based on convenience
- Used if the desired sample characteristics are very rare. Reliance on referrals from initial subjects to generate additional sample info, hence reduction in costs while introducing bias since it’s less likely that the sample will represent a good cross-section from the overall population
- non-probability method based on judgement, often associated with convenience sampling. Eg a researcher may draw the entire sample from one “representative” part

- Not efficient to gather data on whole populations
