The random sampling technique used to recruit participants is the most important aspect to consider when evaluating the external validity of a study. It ensures that the sample is representative of the population and that the findings can be generalized to a larger group. The number of people in the sample, the use of multiple measured variables, and the number of significant findings are all important aspects of the study, but they do not directly relate to its external validity.
