Question

Quizplus · Accepted Answer

In a laboratory experiment, researchers have more control over the environment and can manipulate and control extraneous variables. In a field experiment, researchers have less control over the environment and are more likely to have extraneous variables that may affect the results. Therefore, the statement that the laboratory experiment allows greater control of extraneous variables than the field experiment is correct. The other statements are incorrect or overly generalizing.
