William McKinley won in 1896 in part due to newspapers covering the election.
The answer is A
Yea that’s the answer
The correct answer is A) Zimbardo did not use a control group.
The major flaw in the research design of the Stanford prison experiment was that Zimbardo did not use a control group.
A control group was necessary to study a particular variable in prison. He had no alternative group to compare and measure the results of the experiment.
Other mistakes he had were that he was part of the experiment. He participated as the prison superintendent. He was an authoritative figure inside the experiment of the prison and influenced the behavior of his students. He should have a neutral position.
