Random selection is used in experimental research designs
Random selection is the cornerstone of experimental research designs. When coupled with random assignment, random selection allows for researchers to establish causal effects. Random selection is necessary for an experimental research design such as the randomized controlled trial. There are several different types of random sampling techniques used in experimental research designs: Simple random sampling, stratified random sampling, and clustered random sampling.
