Quantitative Research Designs and Methods

Selection of the appropriate sample is critical to the reliability and validity of research methodology. The sample must be representative of the population that is being studied. Researchers often report both the inclusion and exclusion criteria for the sample. There are many different methods for selecting a sample and random sampling provides the high control of outside variables but is often difficult to utilize in many studies.
