Abstract
Scientists have been studying gender differences for a very long time. The experiment we’ve done is to test if there is any difference between males and females on estimating size, which we strongly believed that males are better than females. A pen, a cell phone and a notebook were the objects which were used in the experiment. The three objects were given to the people who was involved in the experiment to estimate size. The actual result we got was just the same with our hypothesis that males are better than females when estimating size, however, some people’s result might have effected by other people’s. What’s more , the differences between different gender are more than this, such as brain difference and physical differences.

Introduction :
There are a lot of scientists who have studied the sex differences in spatial abilities. They designed different kinds of experiments to test this. The purpose of this experiment is to see if different genders has the effect on estimate size. A report in Psychology Press named Consequences of severe visual-spatial deficits for reading acquisition: Evidence from Williams syndrome suggested that the difference might also caused by DNA. The experiment is about a difference that might caused by DNA which is estimating size. In this experiment, the hypothesis is that males are usually better at estimating size than females.

Methods:
Ten males and ten females from age 20 to 40 were tested in the experiment. They were chosen randomly in a coffee shop. Each of then was asked to estimate three different objects, which are the length of a pen, the length of a cell phone and the surface area of a notebook. They were allowed to hold those objects and compare them. The number that men and women got has been filled in the chart and be analyzed.

Results:
| |Length of a pen(cm) |Length of a cell phone(cm) |Surface area of a notebook(mm^2) | | |♂ |Diff. |♀ |Diff. |♂ |Diff. | |Actual length: |15 |11.6 |446.04 |

The chart above is a summary the data which has been collected. It shows males’ and females’ estimation on three different objects. As it can be seen, the number of estimation that men had are closer to the actual length and area, especially that of one male who got the exact number with the actual number. Differences between the number people said and the actual length was greater for females than males, it is clear that on the surface area of a notebook section males and females had a huge difference. As it can be seen, the greatest difference is 3.4 centimeter for females and it is -0.6 centimeter for males.

Discussion:
The hypothesis I made was that males are better at estimating size than females. It can be seen that the errors that females made are greater than the differences that males made. This supported my hypothesis. As the results showed, when they estimating the length of the pen, one of those males actually got the exact number with the actual number, however, we can not ignore the possibility of affecting by other factors, because they were all in the same coffee shop, some people’s answer might heard by others.

The differences of ability between females and males are more than estimating size, such as biological differences which is the most obvious one. According to Gender Differences Are Real by Frank York ,“Men and women process information differently because of differences in a portion of the brain called the splenium, which is much larger in women than in men, and has more brain-wave activity.” Brain structural differences cause males and females think differently. That is why they get information and analyze in two different perspectives. This can...
