This is a quick overview of the methods for collecting data that will be studied in this chapter: sample surveys, census, observational studies, and experiments. To get a stratified random sample, start by classifying the population into groups of similar individuals, called strata. then choose a separate srs in each stratum and combine these srss to form the sample. First classify the population into groups of similar individuals, called strata. then choose a separate srs in each stratum and combine these srss to form the full sample. Randomized comparative experiments showed that the third brake light reduced rear end collisions as much as 50%. however, after all manufacturers began installing the third brake light, research showed only a 5% reduction in the number of rear end collisions.
