Question

A psychologist first conducted a study on helping behavior with a sample of college undergraduates. This psychologist then replicated the study using the same procedure with a different participant sample. If similar results were obtained with both samples, this experimenter has demonstrated __________.

Answer 1

External validity

Step-by-step explanation:

• External validity means that the results of the study can be generalized to other conditions, people, stimuli, and time.
• Therefore, replication is essential in experimental research, meaning that studies are usually conducted with different subject populations or in different settings and then have the same results.
• Thus, the conclusion of the researchers can be generalized to a larger population.
