What is convenience sampling in research?

In probability sampling, each element in the population has a known nonzero chance of being selected through the use of a random selection procedure.

What is convenience and purposive sampling?
A convenience sample is the one that is drawn from a source that is conveniently accessible to the researcher. A purposive sample is the one whose characteristics are defined for a purpose that is relevant to the study.

Why do we use convenience sampling in research?

What is a convenience sample in statistics?
Convenience sampling is the most common form of nonprobabilistic sampling, mostly because it is misused. Convenience sampling is a method of collecting samples by taking samples that are conveniently located around a location or Internet service.
Can you use convenience sampling in quantitative research?

Can convenience and purposive sampling be used together?
The terms purposive sampling and convenience sampling are often used interchangeably, but they do not mean the same thing. Convenience sampling is when researchers leverage individuals that can be identified and approached with as little effort as possible.
