A research study has high external validity when:
  1. It measures what it is supposed to measure
  2. The results can be generalized to other age groups
  3. The changes seen in the dependent variable are not caused by such factors as the experience of the scientists
  4. Its result cannot be generalized to both sexes.
Explanation
Answer: B - A research study has high external validity when its results can be generalized to other age groups.
High external validity refers to study results than can be generalized to other people, conditions, and settings.. When a study’s result cannot be generalized to both sexes, the study is said to have low external validity. Measuring the appropriate variables and outside effects to dependent variables are not related to external validity.
