Question

"Most of the researchers prefer probability sampling." Do you agree? Why?

Answer 1

Probability sampling consists of randomized sampling techniques, unlike non-probability sampling which use convenience or mere judgement to sample populations. It is indeed reasonable to say that most researchers prefer probability sampling, because it helps in ensuring that inputs of all kinds from the population have been used in the process of choosing a sample for the study or model.

Using probability sampling techniques like simple or stratified random sampling helps the researcher eliminate bias from the sample - the bias if ignored, as is the case with non-probability sampling, manifests in the form of incomplete or unreliable conclusions and models derived using the sample. Hence, probability sampling is a valuable tool in the hands of researchers using data and statistical tools to perform their studies.
