What are some examples of bias in research studies?

Bias in research studies can manifest in various ways. For instance, selection bias occurs when the sample is not representative of the population.

Can you give me a specific example of selection bias?

Sure! An example of selection bias is a clinical trial that only includes participants from a specific demographic, like young adults, which may not reflect the effects on older adults.

What about confirmation bias?

Confirmation bias happens when researchers favor information that confirms their pre-existing beliefs. For example, a study might only highlight data that supports a hypothesis while ignoring contradictory evidence.

How can researchers minimize bias in their studies?

Researchers can minimize bias by using random sampling, blinding participants and researchers, and ensuring diverse representation in their samples.
