ABSTRACT

            Statistical Analysis is the process of examining data to draw conclusions or insights, and determine cause-and-effect patterns between events; for example determining the safety and efficacy of new drugs by drawing out a probability as to whether the fact that a patient got better (or worse) was due to the drug or some. Statistical Analysis and the methods of preparing a good one has been a problem to most organization both private and government, the implementation of a faulty Statistical Analysis has brought man companies to a close door point were all operations are stopped.  Therefore Statistical Analysis design needs to be accurate and able to give account for every dime spent and on what this money was spent and also give an accurate account and allocation of money to the various departments of the body in study. 

Federal office of statistic Enugu has analysis a lot of issue like rate of arm robbery in the state, child mortality rate, HIV infection, Causes of unemployment etc in their office but for this project work I will concentrate on the child mortality rate and HIV infection.  It is important that there should be a reliable system of Statistical Analysis for every organization and this method is to be computerized for easy flow of work and generation of accurate reports.

CHAPTER FOUR: Design of the system the output specification and input specification and designs are expressed here. File design, procedure and system flow charts are represented with a pictorial diagram the required hardware and soft ware for the new system.

CHAPTER FIVE: Implementation, the implementation of the new system is very vital and was implemented on the bases of a designed program pseudo cods source and test run.

CHAPTER SIX: Documentation in order to use this package effectively and efficiently this work is divided into various steps on how to get started.  Procedures and quitting exiting from the software system.

CHAPTER SEVEN: Recommendation and conclusion this chapter concerns the summary of the study, the conclusion drawn from the recommendation to relief the users of source of their problems and suggestions for further studies.

CHAPTER ONE

INTRODUCTION

Developments in the field of statistical data analysis often parallel or follow advancements in other fields to which statistical methods are fruitfully applied. Because practitioners of the statistical analysis often address particular applied decision problems, methods developments is consequently motivated by the search to a better decision making under uncertainties.

Decision making process under uncertainty is largely based on application of statistical data analysis for probabilistic risk assessment of your decision. Managers need to understand variation for two key reasons. First, so that they can lead others to apply statistical thinking in day to day activities and secondly, to apply the concept for the purpose of continuous improvement. This course will provide you with hands-on experience to promote the use of statistical thinking and techniques to apply them to make educated decisions whenever there is variation in business data. Therefore, it is a course in statistical thinking via a data-oriented approach.

Statistical models are currently used in various fields of business and science. However, the terminology differs from field to field. For example, the fitting of models to data, called calibration, history matching, and data assimilation, are all synonymous with parameter estimation.

Your organization database contains a wealth of information, yet the decision technology group members tap a fraction of it. Employees waste time scouring multiple sources for a database. The decision-makers are frustrated because they cannot get business-critical data exactly when they need it. Therefore, too many decisions are based on guesswork, not facts. Many opportunities are also missed, if they are even noticed at all.

Knowledge is what we know well. Information is the communication of knowledge. In every knowledge exchange, there is a sender and a receiver. The sender make common what is private, does the informing, the communicating. Information can be classified as explicit and tacit forms. The explicit information can be explained in structured form, while tacit information is inconsistent and fuzzy to explain. Know that data are only crude information and not knowledge by themselves.

Data is known to be crude information and not knowledge by itself. The sequence from data to knowledge is: from Data to Information, from Information to Facts, and finally, from Facts to Knowledge. Data becomes information, when it becomes relevant to your decision problem. Information becomes fact, when the data can support it. Facts are what the data reveals. However the decisive instrumental (i.e., applied) knowledge is expressed together with some statistical degree of confidence.

Fact becomes knowledge, when it is used in the successful completion of a decision process. Once you have a massive amount of facts integrated as knowledge, then your mind will be superhuman in the same sense that mankind with writing is superhuman compared to mankind before writing. The following figure illustrates the statistical thinking process based on data in constructing statistical models for decision making under uncertainties.

STATEMENT OF THE PROBLEM

It is easy to note that Statistical Analysis entails large volume of work and a whole lot of calculation.  This makes the job very difficult a task to go by. The method of information storage and retrieval processing of accumulated figures is not an easy task in places were there are no sophisticated method of Statistical Analysis analysis.

Inefficient and insufficient records will always result to a poor and inaccurate Statistical Analysis.  The fact that humans cant tackle the ambiguous calculations and complex allocation involved in Statistical Analysis easily without the help from computer this is also a delay factor for the releasing of an accurate Statistical Analysis statement.  This project will implement Statistical analysis system.
