Learning Outcomes: [Credit Emmanuel Addo, Spring 2013]. By the end of the course, the student should be able to:

• Use and understand common statistical terminology.
• Understand data collection methods including designed experiments and sampling methods.
• Know when to use stemplot, histograms, pie charts, bar charts, and box plots to describe a given distribution.
• Calculate and interpret the measures of center and spread.
• Understand the concepts of correlation and linear regression.
• Understand the concepts of randomness and probability.
• Understand and interpret probability distributions such as the normal, student's t- and chi-square distributions.
• State the central limit theorem and understand the concept of a sampling distribution.
• Calculate confidence intervals for means and proportions--one sample.
• Use sampling techniques to test hypotheses for means and proportions--one and two samples, contingency table, and goodness-of-fit.

Academic Integrity: Cheating is not acceptable and will not be tolerated. Consider this: in subtle ways, cheating to get a better grade on an exam can result in lowering the grades of some of your classmates. Certainly this is true when a specific curve is used to assign grades. Even when I don't use curves explicitly, they can be implicit in decisions about writing and grading exams. As required by the policy of American University, I will report all suspected cases of cheating to the Dean's office who will proceed to investigate and adjudicate the issues. Cheating is giving or receiving unauthorized assistance on exams, from other students or other people, from notes, from books, or from the web. When inappropriate copying between students is caught, both parties may be culpable.
