Abstract
This experiment is to test whether this ability is related to gender. The result is that males own better ability on estimating size than females. The objects used in the experiment are mini flashlight, water bottle, pencil case, pen, and school bag. The outcome confirmed the hypothesis: gender differences do affect human abilities.
1.0 Introduction
Through this experiment and research we will know the different abilities between male and female when estimating size. Estimating physical size and volume is a visual spatial ability. Visual spatial abilities are those related to understanding and conceptualizing visual representations and spatial relationships in learning and performing a task (Jocelyn Wishart 2006). My hypothesis of this experiment is males probably are better than females on estimating size.
2.0 Research Methodology

The material that I used in this experiment is a mini flashlight, a water bottle, a pencil case, a pen, and a school bag. Firstly, I recorded the correct size of the objects. Secondly I let the person to see the ruler first so they know the approximate size. Thirdly I let the target to estimate the size of these first objects without a ruler and record his/her assumption. I let some of the object is measured with their hands. After I record all of the 20 people’s result of the size of the object. Then I search for the final result of the research to find out the conclusion.
3.0 Research Results

The table below shows the 20 adolescent guessing results of five objects. The ages of those people were all from

    To setup the experiment we had to use three meter sticks and two standard tennis balls. We took all three of the meter sticks aligning them vertically up against the wall. Taping them into place we were then able to use them to measure the height of the dropping point. Using our eye sight we had to determine how far up the ball bounced up on the meter stick. We then proceeded to find three appropriate heights to drop then tennis ball at. Dropping it three times at each height and then averaging the data. On the soaked tennis ball we would soak the ball for two seconds before each drop. We also measured the weight of each ball before dropping them. After doing this 3 times each and receiving our averages we were able to create our data and see the relationship between the two.…

    Larger body size is one of several traits that can offer a selective advantage and thus can get passed on to future offspring of successful males. The dimorphism is a result of mating pressure. Most primates are sexually dimorphic for different biological characteristics, such as body size, canine tooth size, craniofacial structure, skeletal dimensions, pelage color, and markings and vocalization. However, such sex differences are primarily limited to the anthropoid primates; most of the strepsirrhine primates (lemurs and lorises) and tarsiers are monomorphic. Also, differential parental investment between the sexes accounts for female mate choice. The number of offspring produced by female primates is often limited due to the limited amount of eggs she has so, females choose their mates that possess certain desirable…

    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.…

    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…

    Research has identified differences in several specific cognitive skills as well as in a range of social and personal characteristics. Some differences are apparent from infancy; others do not emerge until late childhood or adolescence. Interestingly, in several skills the differences between boys and girls have shrunk over the last two to three decades. This indicates that socialization and differential experiences play roles in gender differences. Even when gender differences are significant and consistent over time, we still do not fully understand why they exist. Different experiences and socialization are almost certainly involved, but biological factors may also have important…

    The general research topic for this were the sex differences in mental rotation. Twenty- five female students and five male students were assigned to different treatment conditions and were tested on their response time and accuracy in the different mental rotation conditions. It was hypothesized that lateralization between genders would effect the results based on stimulus type. Males were expected to perform better, both in accuracy and speed, with regards to the 2-D shape. On the other hand, females were expected to perform the same as or better than males on the letter ‘R ' mental rotational task. In looking at the independent variables being the two task sessions which were the pointed object and the letter R and that second variable being gender many summaries were made. Table one shows that females were faster in their response time than males. Table two shows that females were also just as accurate as males. These results therefore reject the hypothesis previously stated.…
