Quantitative Methods Questions
Probability sampling is a sampling technique in which each member of the population has a known and equal chance of being selected for the sample. This method ensures that the sample is representative of the population and allows for the calculation of statistical measures such as sampling error and confidence intervals.
On the other hand, non-probability sampling is a sampling technique in which the selection of individuals for the sample is based on subjective criteria and does not involve random selection. This method does not guarantee representativeness and makes it difficult to generalize the findings to the larger population. Non-probability sampling is often used in qualitative research or when it is not feasible to use probability sampling methods.
