Does a larger head mean higher intelligence?

Introduction: Some say a larger head gives room for a bigger, more intelligent brain. Men, thought to have larger heads simply because they're… well men. In which case, men have a larger head size than women, therefore making men smarter than women.

Methods: My partner and I went ahead and measured the heads of 15 people in our class, 5 of them male and 10 of them female. We used a measuring band to measure, to the nearest millimeter, the circumference of their heads. For the men in the class we gathered five measurements: 57, 58, 58, 61 and 60. For the women in the class we gathered ten measurements: 60, 56, 58, 55, 57, 59, 58, 54, 57 and 61. To be sure, we measured everyone twice with two different measuring tapes. We came out with the same numbers both times. After getting our measurements, we first added up the measurements for the men and divided by five to get the average head circumference. We then did the same with the female measurements but divided by ten.

Results: After adding up our measurements, the average head circumference of the men in the class was 58.8mm. The average head circumference of the women in the class was only 57.5mm.

Conclusion: According to our results, the hypothesis would be true. Although, I reject the hypothesis. Some men can very well have a larger head size and be more intelligent than a woman, but same could be said for women. Simply measuring the circumference of one's head could never actually tell you how intelligent someone is. The best way to accurately say that men are smarter than women is to actually test their intelligence with a series of tests in different subjects such as Math, Science and History.

The tooth formula is a shorthand technique that biologist use to keep track of the teeth on a particular jaw. The formula consisted of two lines, top jaw and bottom jaw, which were used to count how many incisors, canines, premolars, and molar teeth a species had. Species A, Odocoileus virginiaus (white-tailed deer), had a tooth formula of 0033/3133. On the top jaw, the deer had zero incisor and canine teeth but have three of both the premolars and molars. On the bottom jaw, the deer had three incisors, one canine, three premolars, and three molars. Species B, Canis latrans (coyote), had a tooth formula of 3142/3143. On the top jaw, the coyote had three incisors, one canine, four premolars, and two molars. On the bottom jaw, the coyote has three incisors, one canine, four premolars, and three molars. Both the deer and coyote skull were long and skinny towards the nose and mouth. The coyote skull had a much rounder nose than the deer. Species C, Homo sapiens (human), had a tooth formula of 2122/2122. On both the top and bottom jaws, there were two incisors, one canine, two premolars, and two molars. In comparison to the deer and coyote skull, the human was an outcast. The human skull was a short distance from the back of the skull to the front. The human skull was very different in bone structure and longer in height than the deer and coyote skulls.…

In his essay, “Women’s Brains”, Stephen Jay Gould discusses the incorrect and often biased research of women’s intelligence based on data written by craniometrometer Paul Broca. While Gould does not come out and blatantly say it, I believe that he is using this essay to appeal to a more open minded individual who will take the data presented to them, and formulate their own opinions and ideas based off of what Gould has projected. I believe that Gould is actually a very liberal-minded person, and is uses this essay to subtly recognize the change and contrast between the female standings in the 1800s, and the female standings in present day.…

"Men Peek Out of the Cave" by Peder Zane promoted a ton of thoughts for me, as a women hoping to ascend into a higher educated position of leadership, this essay was a confidence creator and a depression causer. Zane wrote in his essay that "six out of ten recipients of bachelor's or master's degrees are women, and the gap is widening." This tells me as a woman that women are starting to beat the stereotype that females are less intelligent then women but this isn't necessarily true either as read of further into the essay.…

Men's lack of intelligence is apparent from Grendel's first encounter with men. Though in some ways sad, when the men have Grendel's unconscious body and they think that the giant beast with human-like features is a tree fungus, and then a spirit, you can't help but laugh at how just plain dumb these men are. "The tall one said, It's a growth of some kind, that's my opinion. Some beastlike fungus.'"(Gardner 24) This quote is just a great example of the logic skills these men have. Just as great of an example as that last sentence was of sarcasm.…

Everybody knows that boys and girls are very different. They look different, act different, like different things, perform differently in school and sports, and are just different people! Studies have shown multiple differences in how male and female brains function differently. One of the most interesting differences is how the male brains process language, estimate time, judge speed, carry out mental math calculations, view the orientation of space, and visualize three dimensional objects better then women. Women are better at human relations, recognizing emotional overtones in others and language, emotional artistic expressiveness, esthetic appreciation, verbal language, and carrying out pre- planned tasks. Scientists think that this might explain why there are more men…

The height to arm-span was 1cm different for the mean but as for the median and mode; they were both out by 4cm. The hand length was within 1cm for mean but the median and mode was around 6 cm out of proportion. The foot length in mean is 2cm out of proportion but then again the mode is out by 4cm and median is out by 5cm. The elbow to hand tip was 3cm out of proportion for mode and mean but median the elbow to hand was out of proportion by about…

In terms of school age pupils, I believe that over all girls are slightly more intelligent than boys. For this piece of coursework I am going to investigate if my hypothesis: "girls are more intelligent than boys" is true. In my opinion I believe this statement is more or less correct because in the years I have been in at school, the majority of pupils who consistently performed the best by getting the best examination and test results each year, were mostly made up of girls rather than boys. Also, because of tests and surveys, it has been widely publicized in the past that girls are more intelligent than boys - this seems to back up my statement. * In order to undertake this piece of coursework, I have been issued with a fictional database, which consists of two fictional year groups: year 10 and 11. In these year groups are the features of hundreds of fictional pupils such as each individuals: IQ, height, weight, eye colour, the number of hours of television they watch each week and their gender. From this database I will use the information, which comprises of each pupils IQ - as this is the information in which I will need in order to research and to find out if my hypothesis is true - if girls are more intelligent than boys. Through the course of this coursework I will undertake a number of calculations (which I will list after I have arranged my chosen pupils in a table) that are based upon the IQ of the pupils that I will choose from the fictional database. I will carry out these calculations in order to come to some conclusion to whether my hypothesis is correct - if girls are more intelligent than boys. Firstly, I have used the database handed to me to calculate the number of boys and girls in each year group for future reference. I will add together the total number of boys in year 10 and 11 and the total number of girls in year 10 and 11 so that I will be able to compare the two genders, once I have selected the pupils I will be examining and using for…
