This calculator wil be allowed on most assessment opportunities in this course. Fundamentals of StatisticsBy Sullivan (Prentice Hall) RecommendedEssential Statistics: Exploring the World Through DataBy Gould and Ryan (Pearson) Recommended Course Objectives To choose appropriate statistical methods to solve real-world problems and understand the limitations of the methods in making predictions and drawing conclusions. To use appropriate technology to solve statistical problems. To organize data, communicate the essential features of the data, and interpret data in meaningful ways. To understand the role of probability in the foundation of modern statistics methods. Measurable Learning Outcomes: Classify data as qualitative or quantitative (discrete or continuous). Identify advantages and disadvantages of sampling and of common sampling methods. Distinguish between observational studies and experiments and define different types of experimental design. Construct frequency distributions for qualitative data and frequency distributions, histograms, stem and leaf plots, and boxplots for quantitative data. Describe distributions of quantitative data in terms of shape, center, and spread. Explore the relationship between two qualitative variables using two-way tables. Explore the relationship between two quantitative variables using scatterplots.  Compute and interpret regression lines and correlation coefficients.  Compute probabilities using the addition rule, the multiplication rule, complements and simple counting techniques. Determine if events are independent using conditional probabilities. Construct discrete probability distributions. Compute and interpret the mean (expected value) and standard deviation of a discrete random variable. Compute probabilities of binomial experiments. Compute probabilities and find percentile values of normally distributed data. Determine if a data set is approximately normally distributed. Describe and explain the concept of a sampling distribution and the statement of the Central Limit Theorem. Compute point estimates and interval estimates for a mean or proportion. Determine the sample size necessary for estimating a mean or proportion to within a given margin of error. Test hypotheses for a mean or proportion using P-values.

NOTE: The intention of this master course syllabus is to provide an outline of the contents of this course, as specified by the faculty of Columbia College, regardless of who teaches the course, when it is taught, or where it is taught. Faculty members teaching this course for Columbia College are expected to facilitate learning pursuant to the course objectives and cover the subjects listed in the topical outline. However, instructors are also encouraged to cover additional topics of interest so long as those topics are relevant to the course's subject. The master syllabus is, therefore, prescriptive in nature but also allows for a diversity of individual approaches to course material.
