Stratified Sampling in R A high school is composed of 400 students who are either Freshman Sophomores Juniors or Seniors. Stratified random sampling is a type of probability sampling using which researchers can divide the entire population into numerous non-overlapping homogeneous strata. For example geographical regions can be stratified into similar regions by means of some known variables such as habitat type elevation or soil type.
