What is a key advantage of observational studies?

Back

Observational studies allow researchers to collect data in real-world settings, providing insights into natural behaviors without the influence of experimental conditions.

Front

What is a disadvantage of observational studies?

Back

A disadvantage of observational studies is that they cannot establish cause-and-effect relationships due to the lack of manipulation of variables.

Front

What is a key advantage of experiments?

Back

Experiments can establish cause-and-effect relationships by controlling variables and using random assignment.

Front

What is a disadvantage of experiments?

Back

Experiments may lack ecological validity, meaning the results may not generalize well to real-world settings due to controlled conditions.

Front

What is a key advantage of surveys?

Back

Surveys are efficient for collecting data from a large population and can be administered in various formats.

Front

What is a disadvantage of surveys?

Back

Surveys can be flawed by non-response, leading to biased results if certain groups do not participate.

Front

What is the purpose of random selection in surveys?

Back

Random selection ensures that every individual in the population has an equal chance of being chosen, which helps to create a representative sample.
