What are some real-world examples of sample bias?

What are some real-world examples of sample bias?

Sample bias occurs when a sample is not representative of the population. One example is in medical research, where predominantly male participants are studied, leading to results that may not apply to women.

Can you give another example?

Sure! In political polling, if a survey only includes responses from urban areas, it may not accurately reflect the opinions of rural populations.

How does sample bias affect decision-making?

Sample bias can lead to flawed conclusions and poor decision-making, as decisions based on biased data may not address the needs of the entire population.

What can be done to minimize sample bias?

To minimize sample bias, researchers can use random sampling methods, ensure diverse representation, and conduct thorough demographic analyses.
