Questions and Answers
What is a primary characteristic of non-probabilistic sampling techniques?
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?
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 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.

Non-Probabilistic Sampling
Non-Probabilistic Sampling
Sampling techniques where selection criteria are set, but not all individuals have equal chances of being chosen.
Quota Sampling
Quota Sampling
Non-probabilistic sampling that focuses on pre-defined characteristics of a population, selecting a specific number of individuals for each trait.
Representativeness (Non-Probabilistic)

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.
