Which term refers to the grouping of subjects based on certain characteristics before sampling?

Stratification
Segmentation
Distribution
Classifying

The correct answer is: Stratification

The term that refers to the grouping of subjects based on certain characteristics before sampling is stratification. This method is commonly used in research and statistics to ensure that different subgroups within a population are adequately represented in a sample. By identifying key characteristics and categorizing individuals accordingly, researchers can enhance the precision of their data and the generalizability of their findings. For example, in a study investigating community health, a researcher might stratify the sample by age, gender, and socioeconomic status. This allows for a more comprehensive analysis of how health outcomes may vary across these different groups, improving the overall validity of the study. Stratification is particularly useful when certain characteristics are believed to influence the outcome being studied, enabling researchers to make informed predictions and conclusions based on more representative data.
