Introduction
It is still unclear whether sex hormones (male or females) affect on the ability humans have on the estimation of sizes. Research shows that androgens increase the performance of spatial abilities in humans, although this can compromise verbal fluency abilities, making males more efficient than females when estimating 3D spaces. The purpose of this experiment is to know if males are better than Females when estimating sizes. Methodology

For this experiment 10 Females subject and 10 Male where needed. All of them are around the age of 18-23 years old, and same sociocultural environment. The material that was used was going to be 2 pieces of red ribbon that have different sizes. The first ribbon was going to measure 120cm, and the second ribbon was 50 cm. This ribbons where hanged at a distance of 3 m from every subject. Then, all the subjects were asked to make an approximate calculation on how large both ribbons where. All the data was written down and then put into a table in order to analyze the answers.

Analysis
As shown in the results, it is seen that males have a lower margin of mistake than females, by a difference of 12.7 cm. That means that males have an advantage over females when it comes to spatial abilities. While analyzing the results in the table, it can be seen that females tend to round up and give a familiar number, making a less accurate approximation. While males, tend to say and exact and odd number that they think of, and that makes them have a more accurate and closer estimation of the ribbons. Only one subject (male) was able to give the exact length of a ribbon (ribbon #2). Discussion

When it comes to performing activities that require spatial skills, like navigating in a 3D space or giving directions, men generally do better. Females use the cerebral cortex for solving problems that require navigation skills. Males use an entirely different area, mainly the left hippocampus that is located deep inside the brain, and it is not activated in the female's brains during navigation tasks. The left hippocampus, automatically scans where you are in space. As a result, females are more likely to rely on landmark cues such as “Turn at the 7-11 and make a right at the church”, while males are more likely to navigate with deeper detail such as “Go east, then west, etc”. Three-dimensional mental rotation tasks are the best example to test and compare the domain of spatial abilities in gender matter. Mental rotation abilities, are the abilities a human has to imagine objects from a different perspective other than the one that it is shown to them. Gender differences in mental rotations have been observed in African, and East Indian populations, as well as in Western cultures. Gender differences in...
