Description

CALENDAR DESCRIPTION:

The standard techniques of multiple regression analysis, analysis of variance, and analysis of covariance, and their role in experimental research. Students with credit for STAT 302 may not take this course for further credit.

COURSE DETAILS:


Lab Instructor: Marie Loughin

Course Outline:

This upper division course introduces students to modelling relationships between a quantitative response variable and both quantitative and categorical explanatory variables. Students will be given the opportunity to practice through the analysis of data provided by the instructor. Students will also work in groups to test their own hypotheses, first collecting data from a simulated population, then using course methodologies to analyze the data, and finally interpreting the results of the analysis in the context of their hypotheses.

R will be used for analysis, using either the Jupyter online platform or RStudio downloaded (free) to a computer. R is available on all computers in SFU’s computer labs. Drop-in help for course concepts and assignments, including use of R, is available through the Statistics Workshop.

iClickers will be used in class. Bonus marks will be given for iClicker participation.

  1. Review: Important concepts from the first course in statistics will be reviewed in the context of statistical models.
  2. Simple linear regression (SLR): models summarizing the relationship between two quantitative variables. This includes the estimation and interpretation of model parameters, assessment of the model’s fit, inference, and prediction.
  3. Multiple regression: constructing models in which several explanatory variables combine to help explain the variability in a quantitative response variable. This includes model assessment, comparison of two regression lines, interactions between explanatory variables, and multicollinearity. Additional topics may include identifying unusual points, variable selection, and/or coding categorical predictors.
  4. Analysis of variance (ANOVA): Use of models to compare means of a quantitative response variable between groups defined by a categorical explanatory variable (e.g. a treatment variable). Includes model assessment and inference for comparison of means. If time allows, other topics in ANOVA may be included, such as analysis of covariance, tests for homogeneity of variances, the problem of multiple testing, and/or block designs.
Midterm exams will take place in the evenings of the dates provided below.

Graduate Studies Notes:

Important dates and deadlines for graduate students are found here: http://www.sfu.ca/dean-gradstudies/current/important_dates/guidelines.html. The deadline to drop a course with a 100% refund is the end of week 2. The deadline to drop with no notation on your transcript is the end of week 3.

Registrar Notes:

SFU’s Academic Integrity web site http://www.sfu.ca/students/academicintegrity.html is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating.  Check out the site for more information and videos that help explain the issues in plain English.

Each student is responsible for his or her conduct as it affects the University community.  Academic dishonesty, in whatever form, is ultimately destructive of the values of the University. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the University. http://www.sfu.ca/policies/gazette/student/s10-01.html
