What is the margin of error in medical research?

The margin of error in medical research refers to the range within which the true value is expected to fall. It indicates the uncertainty of the results.

How is the margin of error calculated?

It's typically calculated using statistical methods, considering sample size and variability. A larger sample size usually results in a smaller margin of error.

Why is it important to understand the margin of error?

Understanding the margin of error helps in assessing the reliability of research findings and making informed decisions based on those results.

Can you give an example of a study with a margin of error?

Sure! For instance, a clinical trial might report a 5% margin of error, meaning the true effect of a treatment could vary by that percentage.

What happens if the margin of error is too high?

If the margin of error is too high, it may indicate that the results are not reliable, leading to potential misinterpretations in clinical practice.
