Statistical Thinking and Model Building
STATISTICAl ANALYSIS

In the evolution of any scientific discipline there is a period in which attempts are made to develop mathematical theories in order to account for and explain the observations generated by the phenomena with which the discipline is concerned. During this period, the qualitative and verbal theories are replaced, or supplemented, by quantitative and mathematical theories which express, in the form of some type of equation or equations, a postulated mechanism or model that can generate a theoretical set of observations. The theoretical and experimental observations can then be compared in order to see if the model is a reasonable one, i.e., if it is capable of accounting for the experimental observation obtained under the conditions stipulated by the data analysis.
Analysis of data is a process of inspecting, cleaning, transforming, and modeling data with the goal of discovering useful information, suggesting conclusions, and supporting decision making. Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, in different business, science, and social science domains. When analyzing the data , we can select one of two approaches to the study of the phenomenon concerned. These two approaches, which are termed deterministic and stochastic (or probabilistic), reflect the casual nature of the postulated mechanism (or model) which we express in mathematical form. It is not of great interest to ask if the phenomenon with which we are concerned is deterministic or stochastic. We are concerned with the analysis of a variable or stochastic model, the investigation of its properties, and its ability to account for experimental observations. The analysis of data or model building involve huge computational complexities. To reduce the burden of computational complexities statistical packages are developed. The term s data analysis refers to the mathematical abstraction, pattern, or

    Data is a collection of facts that can be measured or translated. Data may consist of words, numbers, observations, descriptions of things, and measurements. Data may be qualitative or quantitative. “Qualitative data is descriptive information that describes something. Quantitative data is continuous measurements of numerical information” (Lind, Marchal, & Wathen, 2011, p. 9). Data can be collected in many ways but the simplest way is direct observation. Understanding data analysis helps people to make an informed decision.…

    This chapter taught me the importance of understanding statistical data and how to evaluate it with common sense. Almost everyday we are subjected to statistical data in newspapers and on TV. My usual reaction was to accept those statistics as being valid. Which I think is a fair assessment for most people. However, reading this chapter opens my eyes to the fact that statistical data can be very misleading. It shows how data can be skewed to support a certain group's agenda. Although most statistical data presented may not seem to affect us personally in our daily lives, it can however have an impact. For example, statistics can influence the way people vote on certain issues.…
