# STATS 208 : Data Analysis for Commerce

## Science

### Course Prescription

A practical course using the popular R language in the statistical analysis of data and the interpretation and communication of statistical findings. Includes exploratory data analysis, analysis of linear models including multiple regression and analysis of variance, generalised linear models including logistic regression and analysis of counts, time series analysis.

### Course Overview

This is a practical course in statistical data analysis with a heavy emphasis on interpretation and communication of statistical findings. The core of the course covers linear models but also includes an introduction to categorical data, generalised linear models and time series. The course is taught using the R computing environment with an emphasis on reproducible research. This enables you to answer many of the commonly encountered quantitative scientific questions of interest. STATS 208 is for any students enrolled in the commerce faculty. Students wishing to get a major/minor in statistics should have done this course.

https://www.auckland.ac.nz/en/science/study-with-us/maori-in-our-faculty.html

Statistics has a Tuākana Programme where there is a workspace and a social space shared with Science Tuakana students. Tutorials and one-to-one assistance are available. Tuākana tutors/mentors work alongside the lecturer to support students with assignments and revision for the quizzes and exams. For more information and to find contact details for the Statistics Tuākana coordinator, please see https://www.auckland.ac.nz/en/science/study-with-us/maori-and-pacific-at-the-faculty/tuakana-programme.html
Contacts are Susan Wingfield (s.wingfield@auckland.ac.nz) and Heti Afimeimounga (h.afimeimounga@auckland.ac.nz).

### Key Topics

• Linear Models: Introduction to R. Simple Linear Models. Assumptions of the linear model. Model checks and inference. Null model (one-sample t-test). Paired t-test. Fitting curves using linear models. Quadratic models. Using categorical variables as explanatory variables. Two-sample t-tests. Multiplicative models. Working on the log scale. Power law models. Models with categorical and numeric explanatory variables (ANCOVA). Models with several explanatory variables. Multiple linear regression. Explanatory factor with multiple levels – One-way ANOVA. Multiple comparisons problem. Two-way ANOVA.
• Categorical Data and Generalised Linear Models: Count Data. The Poisson distribution. Using Poisson regression via generalised linear models (GLM). Binary responses. Using binomial GLM. Modelling data from tables of counts. Odds ratios.
• Time Series: Components of a time series. Time series plots. Forecasting. Modelling time series.

### Special Requirements

The test will be held during the evening.

### Workload Expectations

This course is a standard 15-point course and students are expected to spend 12.5 hours per week involved in each 15-point course that they are enrolled in.
For this course, a typical weekly workload includes:
• 3 hours of lectures
• 5-6 hours of reading and thinking about the content
• 4 hours of work on assignments and/or test preparation (including up to 12 hours of optional tutorials)
For Summer School Courses, you should double this as they are taught at twice the speed.

### Delivery Mode

#### Campus Experience

Lectures will be available as recordings.
The activities for the course are scheduled as a standard weekly timetable.
Attendance in person will be  required for any on campus test and exam.

### Learning Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

Other Materials:
• All learning resources are available on Canvas

### Student Feedback

During the course Class Representatives in each class can take feedback to the staff responsible for the course and staff-student consultative committees.

At the end of the course students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback.

Your feedback helps to improve the course and its delivery for all students.

Student Assistance Hub has proved to be an extremely valuable source of help, but more help was requested leading up to assignments, so we are looking at increasing staffing levels on weeks that assignments are due.

### Academic Integrity

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed for potential plagiarism or other forms of academic misconduct, using computerised detection mechanisms.

### Class Representatives

Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.
