You will learn a scientific method of gathering unbiased data, applying probability rules, using statistical calculations (often with the help of the TI-84 graphing calculator), and drawing well-supported conclusions from the data to answer the research question. The course requires strong analytical skills, a willingness to learn and follow the scientific method that supports accurate decision-making in the presence of uncertainty, and an ability to write and explain your conclusions in a clear, concise, and persuasive way.
