Course Objectives Building on prior coursework in statistical methods and modeling, students will gain a deeper understanding of the entire process of data analysis, using both frequentist and Bayesian tools. The course aims to develop skills of model selection and hypotheses formulation so that questions of interest can be properly formulated and answered. An important element deals with model review and improvement, when one's first attempt does not adequately fit the data. Students will learn how to explore the data, build reliable models, and communicate the results of data analysis to a variety of audiences.
Course Contents & Topics Descriptive statistics, presentation and visualization of data; Simple statistical analyses for the one-sample and two-sample case; Regression analyses: model fitting; variable selection and model diagnostic checking; Bayesian inference: prior distributions, conjugate models, posterior summaries, Bayesian hypothesis testing; Analysis of Variance (ANOVA).

Real data sets will be presented for modelling and analysis using statistical software for gaining hands-on experience.
Course Learning Outcomes
On successful completion of this course, students should be able to:

CLO 1 identify the association among several continuous or discrete variables
CLO 2 summarize and describe quantitative and qualitative properties of data using simple appropriate statistical measures
CLO 3 carry out comprehensive statistical analyses on real data using frequentist and conjugate Bayesian techniques for regression, hypothesis testing and model selection
CLO 4 formulate testable hypotheses, carry out appropriate statistical inferences, interpret findings and summarize in written reports
Pre-requisites
(and Co-requisites and
Impermissible combinations)		 Pass in STAT3600 or STAT3907
(Students are strongly recommended to take STAT2604 prior to taking this course.)
