How would you decide between stratified sampling and cluster sampling? Deciding between stratified sampling and cluster sampling depends on the specific objectives of the survey, the nature of the population, and practical considerations like cost, time, and logistical ease. Here’s a breakdown of when to use each method based on key factors: 1. Population Homogeneity or Heterogeneity: Stratified Sampling : Use when : The population is heterogeneous, meaning it contains dist
