This course is a study of basic descriptive and inferential statistics. Topics include types of data, sampling techniques, measures of central tendency and dispersion, elementary probability, discrete and continuous probability distributions, sampling distributions, hypothesis testing, confidence intervals, and simple linear regression.

The purpose of this course is to enable students to select and apply appropriate descriptive and inferential statistical techniques to analyze varying types of data, to defend the rationale for selection of the techniques and to effectively communicate results to their analyses. It will prepare students for techniques used in upper level management courses and provide them with the knowledge necessary to evaluate statistics as they are used and/or misused in business, politics, and other fields.

1. Summarize and make appropriate conclusions about data by using appropriate graphical displays and by calculating and interpreting measures of central tendency and dispersion. Calculate z-scores and percentiles.

2. Calculate probabilities of events and unions, intersections and complements of events using basic counting rules and the basic laws of probability.

3. Calculate probabilities using binomial, Poisson and normal distributions.

4. Explain the importance of randomness in sampling, select and apply appropriate sampling techniques.

5. Calculate confidence intervals for population means or proportions from sample data using the normal distribution for large samples and student’s t-distribution for small samples and interpret the result.

6. Test hypotheses concerning population means and proportions using either large or small sample data and interpret results.

7. Calculate confidence intervals and perform hypothesis test for differences in two population means or proportions and interpret the results.

8. Communicate the results of statistical analysis in a clear and concise manner.

9. Be a critical consumer of statistics presented by the media and other sources. Accurately interpret the statistics presented, identify ways in which they might be subject to misinterpretation either intentional or unintentional and apply ethics to the interpretation and presentation of statistics.

10. Apply the concepts addressed in the course to problem solving including problems related to business.

Located on the Daytona Beach Campus, the Jack R. Hunt Library is the primary library for all students of the Worldwide Campus. The Chief Academic Officer strongly recommends that every faculty member, where appropriate, require all students in his or her classes to access the Hunt Library or a comparable college-level local library for research. The results of this research can be used for class projects such as research papers, group discussion, or individual presentations. Students should feel comfortable with using the resources of the library.
