Ankney's (1992) research was a revision of previous studies on men and women's brain-size in correlation with intelligence. Ankney decided to reexamine the data of an experiment conducted by Ho, Roessmann, Straumford, and Monroe because he believed they had made an obscene amount of technological errors in their analysis. Ho, Roessmann, Straumford, and Monroe conducted their experiment of 1,261 autopsy records from Cleveland, Ohio. These autopsy records of these subjects raged from the ages of 25 to 80 years old. Ankney did not argue with their results of brain mass because the data was highly significant, overall men had the bigger brain mass than women. However, Ankney did not agree with how they compared brain mass and body size and how they divided each and then calculated a mean…show more content… Ho, Rosessmann, Straumford, and Monroe concluded their results stating that “White women have more brain mass than white men when weight, height, and surface area are adjusted. Black women, have significantly lower brain weight than black men when height and body area are adjusted.” Ankney decided that he was going to use a different technique and analyze the data and plotting and using covariance of the variables. Ankney concluded that after he altered the data’s body surface area and body height in both racial groups that men’s brains were 100g heavier than their female counterparts. The next question that Ankney studied was if men have bigger brains than women; does that make men more intelligent than woman? There is no significant evidence to prove this phenomenon. Ankney found that there was no specific evidence if men and women have any differences when it comes to general intelligence, but there is evidence each have specific abilities that they are better at. For example women are better at motor skills, verbally, and perceptual speed. The brain of a woman is thought to be more efficient than that of a
