Why are representative samples important in research?

Representative samples are crucial because they ensure that the findings of a study can be generalized to the larger population.

Can you explain how a sample can be representative?

A sample is considered representative when it accurately reflects the characteristics of the population from which it is drawn, such as age, gender, and socioeconomic status.

What happens if a sample is not representative?

If a sample is not representative, the results may be biased, leading to incorrect conclusions that do not apply to the broader population.

How can researchers ensure their samples are representative?

Researchers can use random sampling techniques, stratified sampling, or ensure diversity in their sample to enhance representativeness.

Are there any examples of studies that failed due to non-representative samples?

Yes, there are many cases, such as surveys that only include certain demographics, leading to skewed results and misleading insights.
