...IMPORTANCE OF STATISTICS
In today's world we are faced with situations everyday where statistics can be applied. Statistics can be used to determine the potential outcome of thousands of things where the human mind alone wouldn't be able to. Statistics benefits all of us because we are able to predict the future based on data we have previously gathered. Being able to predict the future not only changes our lifestyle but also helps us be more efficient and effective.
Statistics is the science of collection, analysis, and presentation of data. Statisticians contribute to scientific enquiry by applying their knowledge to the design of surveys and experiments; the collection, processing, and analysis of data; and the interpretation of the results.
Statisticians may apply their knowledge of statistical methods to a variety of subject areas, such as biology, economics, engineering, medicine, public health, psychology, marketing, education, and sports.
Many economic, social, political, and military decisions cannot be made without statistical techniques, such as the design of experiments to gain federal approval of a newly manufactured drug.
Statisticians provide crucial guidance in determining what information is reliable and which predictions can be trusted. They often help search for clues to the solution of a scientific mystery and sometimes keep investigators from being misled by false...

Question 1: Give a comprehensive account of the importance of Statistics to you (i) as a government agent, (ii) as a Public Administrator, (iii) as an individual
Statistics, is study of the systematic collection, organization, and interpretation of data. This includes the planning of data collection in terms of the design of surveys and experiments. Is is therefore safe to say that Statistics, as a discipline, is the development and application of methods to collect, analyze and interpret data for future planning and problem solving.
The common goal of a statistical research project is to investigate causality, that is the is the relationship between an event (the cause) and a second event (the effect) where the second event is understood as a consequence of the first and in particular to draw a conclusion on the effect of changes in the values of predictors or independent variable on dependent variables or response. Modern statistical methods involve the design and analysis of experiments and surveys, the quantification of biological, social and scientific phenomenon and the application of statistical principles to understand more about the world around us. Since data are used in most areas of human endeavor, the theory and methods of modern statistics have been applied to a wide variety of fields.

...INTRODUCTION
Statistics and mathematics are everything to economics. infact statistics and Mathematics, the economic field wouldn't even exist.
Economist need statistics to represent data, to track and store information, to identify trends, to attribute value and mathematics to calculate those figures.The way to look at the relationship between statistics and economics is that economics is essentially the study of human decisions and trends, and how these have a financial impact.
Economists rely on information to form analyses, understanding and opinion on the human activity that they are scrutinizing. This information comes in the form of statistical data.
Statistics is the core around which economic deductions are built. It highlights the relationship between figures that would otherwise be meaningless, and is key to economic analysis.
An example of this would be an economist trying to analyze the performance of a car manufacturer over the period of a year.
Figures that show the car manufacturer's sales, profits, costs, and other important economic information would be relayed through the use of statistics.
Although people would be right to argue that economics requires more than just statistics (for example, it also relies heavily on understanding and monitoring of sociological factors), it's undeniable that statistics form an integral part of...

Statistics plays a vital role in every fields of human activity. Statistics has important role in determining the existing position of per capita income, unemployment, population growth rate, housing, schooling medical facilities etc…in a country. The statistical tools like Index number, correlation, time series analysis, regression analysis, hypothesis testing, and multivariate analysis help to analysis data and predict about future. Now statistics holds a central position in almost every field like Industry, Commerce, Trade, Physics, Chemistry, Economics, Mathematics, Biology, Botany, Psychology, astronomy etc…, . So application of statistics is very wide. Statistics helps in providing a better understanding and exact description of a phenomenon of nature. It helps in proper and efficient planning of a statistical inquiry in any field of study by collecting an appropriate quantitative data. Statistics helps in understanding the nature and pattern of variability of a phenomenon through quantitative observations and helps in drawing valid inference, along with a measure of their reliability about the population parameters from the sample data. Statistics...

...techniques.
Firstly we look at data analysis. This approach starts with data that are manipulated or processed
into information that is valuable to decision making. The processing and manipulation of raw
data into meaningful information are the heart of data analysis. Data analysis includes data
description, data inference, the search for relationships in data and dealing with uncertainty
which in turn includes measuring uncertainty and modelling uncertainty explicitly.
In addition to data analysis, other decision making techniques are discussed. These techniques
include decision analysis, project scheduling and network models.
Chapter 1 illustrates a number of ways to summarise the information in data sets, also known as
descriptive statistics. It includes graphical and tabular summaries, as well as summary measures
such as means, medians and standard deviations.
Uncertainty is a key aspect of most business problems. To deal with uncertainty, we need a basic
understanding of probability. Chapter 2 covers basic rules of probability and in Chapter 3 we
discuss the important concept of probability distributions in some generality.
In Chapter 4 we discuss statistical inference (estimation), where the basic problem is to estimate
one or more characteristics of a population. Since it is too expensive to obtain the population
information, we instead select a sample from the population and then use the information in the
sample to infer the...

REFLECTION
The first thing that puffs in my mind when I heard the word STATISTIC is that it was a very hard subject because it is another branch of mathematics that will make my head or brain bleed of thinking of how I will handle it. I have learned that statistic is a branch of mathematics concerned with the study of information that is expressed in numbers, for example information about the number of times something happens. As I examined on what the statement says, the phrase “number of times something happens” really caught my attention because my subconscious says “here we go again the non-stop solving, analyzing of problems” and I was right. This course of basic statistic has provided me with the analytical skills to crunch numerical data and to make inference from it. At first I thought that I will be alright all along with this subject but it seems that just some part of it maybe it is because I don’t pay much of my attention to it but I have learned many things. I have learned my lesson.
During our every session in this subject before having our midterm examination I really had hard and bad times in coping up with this subject. When we have our very first quiz I thought that I would fail it but it did not happen but after that, my next quizzes I have taken I failed. I was always feeling down when in every quiz I failed because even though I don’t like this...

...of 1000 flights and proportions of three routes in the sample. He divides them into different sub-groups such as satisfaction, refreshments and departure time and then selects proportionally to highlight specific subgroup within the population. The reasons why Mr Kwok used this sampling method are that the cost per observation in the survey may be reduced and it also enables to increase the accuracy at a given cost.

...compliments the regular mathematics and therefore both are tested in primary schools. Mathematics is the written application of operation. It teaches students to think clearly, reason well and strategize effectively. Mental Mathematics is the ability to utilise mathematical skills to solve problems mentally. The marks scored by pupils generate statistics which are used by teachers to analyse a student’s performance and development of theories to explain the differences in performance.
The Standard 3 class is where the transition from junior to senior level occurs where teachers expect the transference of concrete to abstract thinking would have occurred.
A common theory by many primary school teachers is ‘Students perform better in Mathematics than Mental math. Mental math is something that has to be developed and involves critical thinking. Mental math requires quick thinking and the student must solve the problem in their minds whereas in regular mathematics, the problem can be solved visually. Therefore, teachers should take these factors into consideration while testing and marking students in these areas.’
In this study, the statistics of 30 students of a standard 3 class of San Fernando Boys’ Government School will be analysed to determine the truth of this theory.
DATA COLLECTION METHODS
Mathematics and mental mathematics marks of term 1 of the class of 2013 were obtained from a Standard 3 teacher of San Fernando Boys’...
