A functionally differentiated society can tolerate extreme differences in the distribution of public and private resources. It can be very broad or quite narrow: maybe you want to make inferences about the whole adult population of your country; maybe your research focuses on customers of a certain company, patients with a specific health condition, or students in a single school. Inclusion and exclusion criteria determine which members of the target population can or can't participate in a research study. eg., fitness, menstrual cycle phase, use of oral contraceptives, risks for certain disease states, tobacco use, no prior exercise within 24 hrs, etc. Interrupted time-series designs: studies that use observations at multiple time points before and after an intervention. Systematic sampling is similar to simple random sampling, but it is usually slightly easier to conduct. Schlosser, R.W., Hemsley, B., Shane, H. et al. The sample should be made independently, i.e., selection of one does not influence inclusion or exclusion of other. %PDF-1.7 % That means the inferences you can make about the population are weaker than with probability samples, and your conclusions may be more limited.
