It is best to select variables that represent the characteristics of the population you are studying. This will help ensure that the sample accurately represents the population and can provide more accurate results. Stratifying based on gender or age alone may not necessarily capture other important variables that could impact the outcome of the study. Stratifying into at most three groups or in order to achieve equally sized groups may not be relevant or feasible for every study.
