Quota Sample

### What is a quota sample? - [ ] A randomly selected group of participants. - [ ] A group selected based on convenience. - [x] A group selected based on specific characteristics or quotas. - [ ] A group selected through systematic sampling. > **Explanation:** A quota sample involves selecting participants based on specific characteristics or quotas set by the researcher. ### Why might a company use a quota sample for a market research study? - [ ] To save time and resources. - [x] To ensure diversity in participant characteristics. - [ ] To achieve a random selection of participants. - [ ] To avoid biases in the research. > **Explanation:** A company might use a quota sample to ensure that the participant group includes diverse characteristics that reflect the population being studied. ### What is a potential drawback of using quota sampling? - [x] It can introduce biases due to the interviewer's discretion. - [ ] It always provides a representative sample. - [ ] It is more time-consuming than random sampling. - [ ] It is expensive compared to other sampling methods. > **Explanation:** A potential drawback of quota sampling is that it can introduce biases because the selection of participants is at the discretion of the interviewer. ### In quota sampling, how are participants selected? - [ ] Randomly, from the entire population. - [ ] Based on geographical location. - [x] Based on specified quotas set by the researcher. - [ ] Through open voluntary participation. > **Explanation:** In quota sampling, participants are selected based on specific quotas set by the researcher to ensure certain characteristics are represented. ### Which of the following is a related term to quota sampling? - [ ] Double-blind study - [x] Stratified sampling - [ ] Content analysis - [ ] Meta-analysis > **Explanation:** Stratified sampling is a related term as it also involves dividing the population into sub-groups, although it is a probability sampling method. ### How are quotas determined in quota sampling? - [ ] By selecting participants from randomly assigned groups. - [x] By using characteristics relevant to the research objectives. - [ ] By convenience or availability. - [ ] By letting participants volunteer to join the study. > **Explanation:** Quotas are determined based on characteristics relevant to the research objectives, ensuring diverse representation in the sample. ### Which is a characteristic of quota sampling? - [ ] It ensures every individual has an equal chance of selection. - [x] It ensures representation of specific characteristics in the sample. - [ ] It relies on random number generation. - [ ] It is always more accurate than random sampling. > **Explanation:** Quota sampling ensures that specific characteristics are represented in the sample, which is essential for studies focusing on diverse population groups. ### Is quota sampling a probability sampling technique? - [ ] Yes - [x] No - [ ] Sometimes - [ ] Only in certain conditions > **Explanation:** No, quota sampling is not a probability sampling technique because it does not ensure that every member of the population has an equal chance of being selected. ### Which aspect makes quota sampling different from random sampling? - [ ] The sample size. - [ ] The choice of participants. - [x] The method of selection based on pre-set quotas. - [ ] The recording of responses. > **Explanation:** The method of selection based on pre-set quotas makes quota sampling different from random sampling, which randomly picks participants from the population. ### Can quota sampling ensure the generalizability of study results? - [ ] Always - [ ] Never - [x] Not necessarily, due to potential biases. - [ ] Only in large-scale studies > **Explanation:** Quota sampling cannot necessarily ensure the generalizability of study results because it may introduce biases due to the non-random selection process.
