How it works
Convenience sampling is a data collection method where samples are chosen solely based on their easy availability and accessibility. While useful for rapid prototyping or preliminary investigations, this method is not statistically sound and can introduce significant biases. For reliable results, it is crucial to transition to data gathered through scientifically designed sampling techniques.
