Social scientists use sampling in social research to make sure that the entire population is being represented. There are two different types of sampling, probability and non probability samples. Sampling has five steps. They are, identifying the problem, specifying a sample frame, specifying the sample method, determining the sample size and then making a plan. Probability sampling is when you use simple random sampling where each person has an equal opportunity to be chosen. Systematic sampling is selected at predetermined intervals. An example would be every 10th customer gets a survey. Stratified sampling is when you select from different categories such as age or gender.
