Convenience Sampling
Definition
Convenience sampling is a non-probability sampling method where individuals are selected based on their easy accessibility or availability. This method often leads to biased results because the sample may not accurately represent the entire population.
Analogy
Imagine you're conducting a survey about favorite ice cream flavors, but you only ask your friends who happen to be at your house at that moment. Your sample would be biased towards the preferences of your immediate circle and might not reflect the preferences of the larger population.
