This statement is generally true. Probability sampling techniques are used for descriptive research because they allow researchers to make statistical inferences about the population being studied. Nonprobability sampling techniques, which do not provide a way to estimate how accurate the sample is, are typically used for exploratory research where the goal is to generate ideas or hypotheses rather than make precise estimates about the population.
