Do males and females have different abilities about estimating size?

Abstract
???The science project I did is about different abilities of males and females in estimating the size of four objects, the weight of the 1st bottle, the width of the television of the classroom, the length of the classroom from front to the back, and the volume of the 2nd bottle. And I think that males have stronger ability to estimating sizes, and the results which I did confirmed my hypothesis. And I shew my point in Discussion. I have tried make less error, and I think that it is scientific.

1.0 Introduction
???I made this survey to show the different abilities between males and females in size estimating. In this world, many animals which are one specie but not same gender are quite different in many ways, such as the ability of finding food, the ability of estimation, etc. I think that men have stronger abilities in estimating size than women do.

2.0 Research Methodology
???In order to investigate exactly, I asked 20 students (10 males and 10 females) of my class to guess 4 different objects. All of the people who I asked were between 16 years old and 17 years old. And the objects which were used to be asked were two kinds of bottles, the classroom and the television of our class room. What I asked were the weight of the 1st bottle, the width of the television of the classroom, the length of the classroom from front to the back, and the volume of the 2nd bottle. And I also used a flexible rule, a steelyard, and a measuring cylinder to get the exact value. And then I got the results.

3.0 Research results
???According to my investigation, it was easy to find the differences between males and females in estimating. In first investigation, the largest number estimated by males was 750ml and the smallest was 500ml. The average number estimate of males was 572ml.For the females the largest and the smallest were 600ml and 450ml. And the average of that was 480ml. The second investigation shew that the longest and the shortest males estimating were 11m and 4m. The average was 7.81m. And the longest and the shortest females estimating were 12m and 4m. The average was 6.85m. The third investigation shew that the longest and the shortest males estimating were 120cm and 50cm. The average was 65.3cm. And the longest and the shortest females estimating were 100cm and 40cm. The average was 70cm. The forth investigation shew that the highest and the lightest males estimating were 750g and 200g. The average was 441g. And the highest and the lightest females estimating were 700g and 100g. The average was 425g.

4.0 Discussion
???According to four investigations results, I made the difference value for four different investigations. The average of difference value of the guessing of the volume of the bottle of males was -35ml. And for females, the average was -127ml. And males difference was bigger than females. It meant that males have stronger estimating ability than females. The average of difference value of the guessing of the length of the classroom from front to the back of males was -0.46m. And for females, the average was -1.42m. And males difference is bigger than females. It meant that males have stronger estimating ability than females. The average of difference value of the guessing of the width of the television of the school of males was -6.7cm. And for females, the average was -2cm. And females difference was bigger than males. It meant that females have stronger estimating ability than males. The average of difference value of the weight of the bottle of males was-171g. . And for females, the average was -187g. And males difference was bigger than females. It meant that males have stronger estimating ability than females.

???All in all, males can estimate better than females.

???According to another three report which was done by other scientist, it was true that males had better ability in estimating sizes than females. But it just depended on the differences in the brain (Luo, 2012). Dr. Pearlson said that the different abilities of estimating size did not mean a superiority or inferiority relationship between men and women (Sabbatini, 1997). And I believed that it was correct.

???The reason why I did these was very necessary today, because this kind of research could help many governments, companies, factories, and some organizations to make good distribution. And it was also helpful for scientists to research the different brains of different gender.

5.0 Conclusion and Recommendations
???In conclusion, as what had been confirmed that it is true that males have stronger estimating ability than females. I think the reason which caused the results which I did was that male and female have different brains. Also they are good at different parts. Or they have different life. These all could lead to the result that males have stronger estimating ability than females. It really suggested that male and female are very different, and they will play different roles in their life.
