  • Not random, not representative

    • Access to hard-reach population: can be easier to establish trust and rapport

    • Cost effective: working from referrals to contact potential participants, take less time + funding to other methods

    • Good for exploratory research:allows researchers to study populations that have not been extensively studied before

    Cons:

    • Sample bias: Participants may be more likely to refer people who share their characteristics or experiences, which can skew the sample. 

    • Difficult to estimate sampling error

    • Slow: because it relies on each participants to recommend other

  • Challenging for other researchers to replicate the sampling methodology accurately

  • It takes less time and money

  • Access Target Population Better

  • Saving time. It’s the ideal choice for gathering primary data within a limited time.

  • Reducing cost because less time is used to gather data.

  • Using in the absence of sampling frames. When the original set of data that samples can be drawn from is absent, the best choice is to apply the quota sampling method.

  • Researcher can conveniently analyze and interpret the responses to the test or survey. This is because the right questions are presented to the right sample group.

  • The quota sampling mostly accurately represents the characteristic of the population.

  • Researcher bias -> the results can be mistakes

  • Cannot calculate the sampling error of the test from one quota because quota sampling is not a probability sampling method.

  • Bias
