Is purposive sampling qualitative or quantitative?

What is the best sampling method?
Random sampling Finally, the best sampling method is always the one that could best answer our research question while also allowing for others to make use of our results (generalisability of results). When we cannot afford a random sampling method, we can always choose from the non-random sampling methods.
What are the five sampling techniques?
There are five types of sampling: Random, Systematic, Convenience, Cluster, and Stratified. Random sampling is analogous to putting everyone’s name into a hat and drawing out several names. Each element in the population has an equal chance of occuring.

What is the difference between convenience sampling and random sampling?
until we had 100 slips of paper. These 100 form our sample.

A convenience sample chooses the individuals that are easiest to reach or sampling that is done easy.
