Questions and Answers

What is a primary characteristic of non-probabilistic sampling techniques?

  • Specific criteria are established for selecting participants. (correct)
  • Every individual has the same probability of being selected.
  • These methods are random and representative of the population.
  • They ensure complete representativeness of the entire population.

    • In a quota sampling method, why is it necessary to understand the target population?

  • To avoid any biases in the selection process.
  • To ensure that every characteristic of the population is represented in the study.
  • To select characteristics that align with the sample size requirements. (correct)
  • To establish a random sample that includes all individuals.

    • When should non-probabilistic sampling techniques be used?

  • When there are restrictions or initial exploration is required. (correct)
  • When a high level of statistical accuracy is needed.
  • When randomness is a priority in research design.
  • When complete representativeness of the population is assured.

    Study Notes

    Non-Probabilistic Sampling Techniques

    • These techniques use criteria to select a sample, not all members have equal chance of selection
    • These methods are less reliable than probabilistic methods as representativeness of the population is lower
    • Useful when strict conditions in a population are required, or when complete exploration is not feasible, and there is no way to obtain a general representation of the population being studied
    • Examples include quota sampling

    Quota Sampling

    • Defining characteristics to establish a sample
    • Sample members are chosen based on certain characteristics that match the population
    • Goal to create a sample that reflects the population
    • Example: A researcher studying product opinions asks 60 young adults and 60 older adults.
