Cluster sampling in the pharmaceutical industry allows researchers to efficiently sample groups of patients or healthcare facilities to study drug treatments' effects.
Cluster sampling is a sampling method where researchers start by sampling groups or clusters of population elements and then select elements from within those groups. In the pharmaceutical industry, cluster sampling allows for efficient sampling of groups of patients or healthcare facilities to study the effects of drug treatments or interventions.
For example, in a study on a new medication's effectiveness, researchers may first sample hospitals as clusters and then select patients within those hospitals for the study. This method helps in obtaining a representative sample while being logistically feasible.
