The course will also build your spreadsheet skills as the analyses will be done using EXCEL for Windows. The classroom time is largely lecture and student problem solving Prerequisite Admission to the College of Business including passing ICS 101 (which also uses EXCEL). Texts:Levine, Krehbeil, and Berenson, Business Statistics: A First Course, Fourth Edition, Prentice-Hall (Required). This explains statistical ideas, statistical tests, and applications.

Chapter 1 Objectives This chapter introduces the field of statistics by linking statistical thinking to the understanding and management of variability. Upon completion of this chapter you should understand: 1. The difference between samples and populations. 2. The difference between categorical and numerical variables. 3. The difference between discrete and continuous variables. 4. The difference between various sampling methods. Why Take Samples from Populations? Less Costly Quicker More Accuracy Feasible To Do Kinds of Samples Random Systematic Stratified Cluster Convenience (see 7.4 for more detail) Measure the Sample With: Categorical Scales Numerical Scales - discrete Numerical Scales - continuous The Idea is to Infer from the Sample to the Population
