• Stratified sampling

• Convenience sampling

• Random sampling

• Quota sampling

What is a disadvantage of stratified sampling?

• It is quick and easy to implement.

• It may not provide a representative sample.

• It is time-consuming and difficult to do.

• It ensures even intervals between subjects.

What is an advantage of stratified sampling?

• It is rarely used in Psychology.

• It is highly representative of the target population.

• It is based on ease of availability.

• It selects every nth individual.

How are participants selected in systematic sampling?

• Based on ease of availability.

• Randomly from the target population.

• Systematically from the target population.

• Based on their proximity to the researcher.

In systematic sampling, what does the variable 'n' represent?

• The total population size.

• The number of people you want in your sample.

• The interval at which individuals are selected.

• The number of groups in the population.

What is a critical factor in determining the reliability and validity of a study's findings?

• Sample size

• Researcher experience

• Study duration

• Data type

What does reliability refer to in research?

• The accuracy of research findings

• The consistency and reproducibility of research findings

• The cost-effectiveness of a study

• The speed of data collection

What is a practical consideration when increasing sample size?

• Decreased accuracy

• Reduced costs

• Resource constraints

• Faster results

What does the term "diminishing returns" refer to in the context of sample size?

• Increased benefits with more participants

• Marginal benefits with more participants

• Decreased costs with larger samples

• Faster data collection with larger samples

What might a larger sample size capture more of, ensuring specific subgroups don't overly influence results?

• Less variability

• More variability
