Answer:
Dr. Binet thinks that children from France are more intelligent than children from England. He gives children from both countries the same test and finds that the French children earned higher scores. He repeats the experiment several times and finds the same result; therefore, his experiment is an example of internal validity . However, since the test was written in French and the English children are only fluent in English, his experiment does not have external validity.
Explanation:
Dr. Binet's experiment is an example of internal validity because it is based on the structure of the experiment (i.e how the experiment is conducted).
An internal validity is based on how the study is conducted. it refers to the extent to which a study establishes a trustworthy cause-and-effect relationship between a treatment and an outcome.
Dr. Binet's using a the French language to test the French and the English student establishes that the result of the experiment is largely affected by the language used.
On the other hand the experiment is said to not have an external validity because it is not applicable in the real world. His conclusion that French children are more intelligent than the English children is not true and his result is only based on the structure of his own experiment.
