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, Loke Ching 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 survey brings 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 necessary things.

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.
