Convenience Sampling
Convenience sampling is a non-probability sampling technique where researchers select participants based on their easy accessibility and proximity, rather than using random selection. It involves gathering data from individuals who are readily available and willing to participate, such as students in a classroom or people at a shopping mall. This method is often used in exploratory research or pilot studies due to its simplicity and low cost.
Developers should learn about convenience sampling when conducting user research, A/B testing, or gathering feedback in agile development cycles, as it allows for quick data collection without the need for complex sampling frameworks. It is particularly useful in early-stage product validation, usability testing with readily available users, or when time and resources are limited, though results may not be generalizable to broader populations.
