Sampling Bias
Definition
Sampling bias occurs when the sample selected for a study is not representative of the population, leading to inaccurate or misleading results.
Analogy
Imagine you're at a pizza party and the host only asks the people who love pineapple on their pizza for their opinion. The resulting data would be biased because it doesn't represent everyone's preferences.
