Survey research design consists of 5 key steps: planning the survey, constructing the survey instrument, conducting the survey, analyzing the data statistically, and analyzing the data qualitatively. There are different types of sampling that can be used including convenience sampling of readily available groups, purposeful sampling of knowledgeable individuals, and probability sampling techniques like simple random and stratified random sampling. Effective survey design addresses what is being investigated, who will be surveyed, how respondents will be selected, and how large the sample size needs to be based on the overall population size.
