Abstract

This report looks to explore the topic of doing males and females have different abilities when estimating size. The point that males’ abilities to estimate size are more accurate than females is hypothesized. To prove this hypothesis, some important information from the internet and a series of related research has been investigated. After collecting the data in my study, the results of this analysis indicate that males have the more accurate abilities in size estimating than females.

Introduction

In the society, male and female have much diversity, which is called ‘Sexual Dimorphism’ in sociology and biology. Such differences are specifically expressed in many different areas in the life, such as morphology, ornamentation, and behavior. The purpose of this report is that analyzing some data to show the different abilities to estimate size for males and females, and trying to find what makes this happened. Now, I would like to hypothesis the males’ abilities to estimate size better than females’.

Methodology

Firstly, some information on the internet about males and females which kinds of people can reckon size accurately will be found. According to the information, ten males and ten females will be chose to make them estimate an item’s (pens, notebooks or shoes) size. For different items, the two gender people may show different abilities in size estimating. At the end of this research, data should be collected and analyzed by charts or other ways to compare the accuracies in size estimating for males and females.

Results

The estimated length of a pen by given ten males and ten females are shown in Figure 1. The actual length of this pen is 14.5cm, which is shown in Figure 1 (a). According to Figure 1 (b), females’ results include some more precise numbers, such as 13.5cm and 14.8cm. Furthermore, the mean value of the estimated length for males is 13.2cm, and for females is 13.82cm, which can be seen clearly that the average estimating of females is more close to the actual length than males.

Figure 1 – (a) the estimated length of a pen by ten males; (b) the estimated length of a pen by ten females.

Table 1 shows the estimated size of a pair of shoes by given ten males and ten females. The size of the shoes is European standard in this research, and actual size is 41. The mean value of the estimated size for males is 41.7, and for females is 40.9, and females have more accurate estimating. | Males’ estimating| Females’ estimating|

Figure 2 reveals the area estimating for a notebook by twenty people from two genders. The actual size of the chosen notebook is 446.25 cm2. Though calculations, the average estimated size is 438 cm2 and 359.25 cm2 for males and...
