Probability.SystematicRandomProbability: Systematic random
定义
- A fixed selection interval is determined by dividing the population size by the desired sample size. A starting point is then randomly drawn from the sample frame, which normally covers the entire target population. From this starting point, units for the sample are chosen based on the selection interval. Also known as interval sampling. For example, a company survey seeks a sample of 1,000 employees out of 10,000 total. Beginning with a random starting number, every 10th name from the employee list of the company will be invited to participate in the study.
