Dr. Guidry might have looked for gender differences in the relationship between the number of friends and life satisfaction to examine her study's external validity. This involves assessing whether the study's findings can be generalized to other populations or settings beyond the sampled elderly men and women in Nashville, Tennessee. By exploring whether the strength of the association differs by gender, she is considering whether the findings are consistent across different groups within the sample, which is a component of evaluating the broader applicability of the results.
