Paper Description

Edit Paper Description Content

STATS221 extends the data collection and analysis techniques introduced in first year statistics courses. It is the gateway paper in the progression of statistical data analysis through to third year level. Students who pass this course will be prepared to cope with standard statistical problems encountered in many fields of research or practice.

The application of statistics is the primary focus of this course. The core topics this paper focuses on are hypothesis testing, ANOVA and regression models. Students will be taught to use the statistical software R to perform useful analyses, interpret the output and convey the results of such analyses. No prior experience with R is assumed.

Paper Structure

Based on encouraging student feedback received for online lectures, this paper will be taught online. All the lectures and lecture material will be available online. The scheduled in-person lectures won't be run. However, one of the scheduled lectures will be run as an in-person workshop/drop-in help session. The workshop will consist of working on problems/questions that will provide a better understanding of the topics taught in the online lectures. These sessions will also double as drop-in help sessions where the students can get in-person help on any questions/queries they may have, including those about using R. Attending these sessions is completely optional and these sessions will not be recorded.

There are no supervised lab sessions for this paper. However, a computer lab in R-block will be reserved for use for STATS221 students to work on assignments throughout the trimester. The lab is reserved so that students can have access to a computer with R installed on it, for learning and working on the assignment problems etc. However, R is a free and open-source software and we recommend students to install it on their personal computers, if they have. Those with personal computers will not need to use the labs at all.

In the unfortunate event of New Zealand moving to higher levels of Covid-19, we are prepared and ready to move this course fully online. The lecturers will notify students of any changes through Moodle
