• 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.
