TERMS TO KNOW
  • Stratified Random Sample

    A random sampling method where individuals are separated into homogenous groups, then simple random samples are taken within each group.

  • Stratum/Strata

    The homogenous groups in a stratified random sample. All individuals in each stratum have something in common, and we would like to see how that affects the outcome of the sample.
