Why is sample size important in research?

Sample size is crucial because it affects the reliability and validity of your research results. A larger sample size generally leads to more accurate estimates and reduces the margin of error.

What happens if the sample size is too small?

If the sample size is too small, the results may not be representative of the population, leading to biased conclusions and lower statistical power.

How do I determine the right sample size for my study?

Determining the right sample size depends on several factors, including the research design, the expected effect size, and the desired level of confidence. Statistical formulas and software can help calculate it.

Can you give an example of a study with a small sample size?

Sure! A common example is a pilot study with only 10 participants. While it can provide initial insights, the findings may not be generalizable.
