The Applied Statistics Handbook was developed to serve as a quick reference for undergraduate and graduate liberal arts students taking research methods. This is an introductory textbook for a first course in applied statistics and probability for un- dergraduate students in engineering and the physical or chemical.

The engineering, or scientific, method is the approach to formulating and solving these problems.
The steps in the engineering method are as follows: 1. Develop a clear and concise description of the problem. Identify, at least tentatively, the important factors that affect this problem or that may play a role in its solution.
Propose a model for the problem, using scientific or engineering knowledge of the phenomenon being studied. State any limitations or assumptions of the model.
Conduct appropriate experiments and collect data to test or validate the tentative model or conclusions made in steps 2 and 3. Refine the model on the basis of the observed data. Manipulate the model to assist in developing a solution to the problem. Conduct an appropriate experiment to confirm that the proposed solution to the problem is both effective and efficient.
Draw conclusions or make recommendations based on the problem solution. The steps in the engineering method are shown in Fig.
Notice that the engineering method features a strong interplay between the problem, the factors that may influence its solution, a model of the phenomenon, and experimentation to verify the adequacy of the model and the proposed solution to the problem.
Steps 2—4 in Fig. Consequently, engineers must know how to efficiently plan experiments, collect data, analyze and interpret the data, and understand how the observed data are related to the model they have proposed for the problem under study.
Applied Statistics is intended to introduce the concepts, definitions, and terminology of the subject in an elementary presentation with minimum mathematical background which does not surpass college algebra.
Applied Statistics should prepare the reader to make a good decision based on data. The material, contained in Applied Statistics, can be covered in a week, 3-hours-per-week semester, with little adjustment as time allows.
It is the 21st century and the technology age, and data is abandunt in every way and field. Statistics is not an exception since it deals with data all, the time. How to make sense of that information was the motive behind writing this treatise on Applied Statistics. Applied Statistics is a compendium, an elementary introduction to the growing field of statistics.
In this consize volume we emphasize on the concepts, definitions and terminology. With no doubt in mind, linking the three building blocks, mentioned above, will provide any person with a strong hold on the subject of statistics.
The material had been presented in such a way that only College Algebra can be a prerequisite for the course that covers the whole text in one semester. The material is presented in 6 chapters. Chapter 1 is about collecting, and organizing qualitative and quantitative data, as well as summarizing the data graphically or numericall regardless if the data were discrete or continuous.
