This document presents the results of a survey conducted by 5 students at Taylor's University on the monthly expenses of male and female students. The survey collected data on spending for various categories such as study materials, food, clothes, travel, and entertainment. Statistical analysis was performed on the data, including calculating the mean, median, mode, and standard deviation for each spending category for both male and female students. The analysis found some differences in average monthly spending between male and female students for most categories. For example, female students on average spent more on clothes but less on food than male students. This survey provides insight into students' spending habits and how they vary by gender.

3. Introduction
This is a mathematics project which is about the “Statistic” conducted by a group of 5
students Kelvin Ng, Tan Wen Hao, Low Jia Cheng, LokeChing Yan and Voon Sze Lun
from Taylor‟s University Lakeside Campus and guided by their lecture Ms. Ann See
Peng. This assignment intended to familiarize us with some of the basic concepts and
skills related to statistic. Statistics is a set of tools used to organize and analyze data. Data
must either be numeric in origin or transformed by researchers into numbers.Statistics is
one of the mathematics which occurs in collection, organization and interpretation of
numerical data especially the analysis of population characteristics by inference from
sampling. For instance, statistics could be used to analyze percentage and it‟s also
frequently used for purposes of prediction. The surveybrings the opportunity and remarks
us about the importance of saving on daily unnecessary expenses. Through the survey, it
shows that the average monthly spending of the students according to their necessary
needs and the entertainment lifestyle as the student. In addition, we learn to find out the
difference of male and female on their monthly expenses. This highlights the spending of
the students and it lets the students to know that they should learn to spend smartly
towards the necessarythings.

4. Objective
The aim of this project gives us to learn how to collect and organize statistical data. For
example, we learn to solve problems when distributing the survey form to people.
Besides, it enables us to apply the knowledge which gained to analyze statistical data and
draw conclusion from the data. Moreover, we can also learn to solve the problems with
various mathematical principles. In addition, we‟re able to present for some simple
statistical data. By doing this assignment, we can also fully understand and apply
fundamental mathematical principles in the way of statistics question. For example, we
learn to use the various types of mathematical principles in our daily life and of course in
the mathematics question. The objective for this project is also to make inferences about
a sample based on information we get from a population and also to use population mean,
as an estimate of the sample mean so that we can get a more accurate results at the end.
In addition, it also makes inferences about a population based on information we get from
a sample taken the population. Through this project, we can also make some inferences
about a sample with a high degree of reliability in order to achieve to purpose. Lastly,
we‟re also able to understand better about the concept of comparative analysis and
gaining more knowledge in understanding the statistical analysis.

38. Conclusion
The survey gives us the opportunity to analyze and solve problems that involve various
mathematical principles. Through the surveys, we learn to collect, organize, present and
draw conclusion for simple statistical data. It also gives us a better understanding to apply
the correct fundamental mathematical principles.
