Question

Quizplus · Accepted Answer

A random sample ensures that every member of the population has an equal chance of being selected, thus increasing the likelihood of the sample being representative of the population as a whole. Oversampling can introduce bias, triangulation is a method of combining multiple sources of data to increase validity, and a case study involves studying a single individual or small group, which may not be representative of the larger population.
