Question

Quizplus · Accepted Answer

The first experiment had external validity, which refers to the extent to which the results can be generalized to real-life settings. This is demonstrated by the fact that the findings were similar to those found in children playing in their homes, indicating that the controlled setting did not significantly alter the behavior of the children. Control (choice A) refers to the degree to which extraneous variables are eliminated in an experiment, while similar independent variables (choice B) refer to the use of the same or similar experimental conditions across different groups. Social interaction (choice D) is not directly related to the design feature being described in this question.
