Probability sampling involves selecting participants or any other unit of interest on a statistically random basis
Its random basis accounts for the more reason why it can also be called Random Sampling
Thus, the selection of each individual participant is based totally on a pre-determined process and has nothing to do with the researchers' discretion
This type of sampling method is commonly applied in quantitative research
Thus, numbers and statistics-based research
This sampling method is very useful for studies whose aim is to produce generalisable findings
Generalisable findings are findings that allow one to draw conclusion about the broader population of interest
Note: probability sampling achieves a random sample
