Description
  

This first course in statistics is designed to introduce students to basic statistical methods and techniques.  Students will learn how you organize and analysis data to support decision making.  Students will also learn how to be more discerning consumers of data presentations and analyses from other sources, such as government and company reports, published research findings, and popular media news coverage.  The course will feature an intensive lab experience using MS Excel.  Topics will include:

 

  • Descriptive Statistics:  Measures of central tendency (mean, median, mode), measures of dispersion (range, standard deviation, variance), graphical data presentation (charts, plots).
  • Probability and Common Distributions:  Definition of probability, basic laws of probability, random variables, discrete and continuous probability distributions (uniform,  binomial), the Normal distribution, Central Limit Theorem, standard error of the mean.
  • Inferential Statistics:  Sample versus population, sampling, hypothesis testing, significance level, Type I and Type II error, tests of distribution parameters, T-Test, confidence intervals.
  • Exploring Relationships among Variables:  Correlations, goodness of fit, linear regression analysis, explanatory versus predictive applications, nonlinear relationships.

Goals and Objectives

Students completing this course should be able to:

 

·        Create, read, and interpret graphs, charts, histograms, and diagrams.

·        Understand and use the basic measures of central tendency and dispersion.

·        Understand and use the language of probability and commonly used probability distributions.

·        Formulate and test hypotheses about population parameters in an appropriate manner.

·       Collect, organize, and represent data, and be able to recognize and describe relationships. 

·      Use MS Excel to analysis datasets in support of business decision making.  

·
