In a research study, a random sample was taken of a binary dependent variable and three independent variables hypothesized to be associated with the dependent variable. A statistical model was developed on the sample data, and the model was then applied to a validation sample. The results of the model were checked to see if the variable distributions were similar to the population from which the samples were taken. This check is related to which dimension of determining importance of results?
A) measurement level
B) external validity
C) internal validity
D) statistical significance

The check to see if the variable distributions in the sample are similar to those in the population is related to external validity. External validity refers to the extent to which the results of a study can be generalized to other situations and to other people. By ensuring that the sample distributions match the population, researchers aim to enhance the generalizability of their findings.
