Overview

Course Prescription

An introduction to mathematical, statistical and computational literacy as required for contemporary biologists. Topics include fundamentals of experimental design, data exploration and visualisation, model-based inference to process biological data into biological information, comparing statistical models, prediction using mathematical models of biological processes, critical thinking about models and effective communication of findings. Data analysis and generation is taught using the R programming language. Recommended preparation: STATS 101

Course Overview

Living systems are the most complex systems in science, and biology is naturally variable and noisy due to its many internal and external influences. For these reasons, it is difficult to make inferences from and predictions about biological systems. Understanding biology requires computational skills to effectively analyse and interpret data, and multidisciplinary research approaches are becoming more common as a critical key to solving many of the complex problems of studying life and living organisms in today’s world. So, contrary to the popular undergrad biology student beliefs, statistics, mathematics and computational skills are essential in a biologist’s toolkit.

To understand modern biological research and findings, and to participate in this research (and get jobs!), skills in working with and visualising data, learning from data using models, and generating data using simulations of models are crucial. These might be classic statistical models, mathematical models, or inference with process-based models. Biologists also need to be careful and critical thinkers about data and how it is acquired with a lens on Data Sovereignty, as well as think critically about the models that we use to try to simplify, and thereby understand, the incredible complexity of biology.

BIOSCI 220 Quantitative Biology must be taken by all students in the Biological and Biomedical Sciences majors as a stage two core requirement. STATS 101 is strongly recommended prior to taking this course, although it is not a prerequisite. This course will introduce you to the programming language R to develop the aforementioned skills, with no coding experience assumed or expected. The aim is to give beginners the confidence to continue learning R and not be afraid of statistics and mathematics!

Advice on Course Limits

This is a limited entry course: there is a limit on the number of enrolments due to staff or space capacity. In cases where the courses is taught under two separate codes (e.g. concurrently taught courses, general education courses) the course limit specified is the total across both versions of the course. For more information, please see the Programme and Course Limitations section of the University Academic and General Statutes and Regulations.

Teaching and Learning

Campus Experience

A Campus Experience means:

  • Attendance is expected at scheduled activities including labs to complete components of the course.
  • Lectures will be available online and as recordings. Other learning activities including labs will not be available as recordings.
  • The course will not include live online events.
  • The activities for the course are scheduled as a standard weekly timetable.

Learning Resources

Taught courses use a learning and collaboration tool called Canvas to provide students with learning materials including 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.

Additional Information on Learning Resources

All course material will be delivered on Canvas. The part of the course that many students nd most challenging is working in "R", a widely-used language for statistical computing. If this is your first time programming (which is common), you should mentally prepare yourself for the fact that (a) everyone finds R challenging at first, but (b) everyone can succeed and make R work for them, and it really is worth it in the end.
You will be given some introduction to R in lectures and labs, but we strongly recommend that R newbies make use of some introductory R tutorials. Beginner tutorials for R/RStudio (there are plenty of more general tutorials available as well): https://education.rstudio.com/learn/beginner/
Swirl tutorials. For a large series of introductory tutorials, open any version of R/RStudio, and in the command prompt type: install.packages("swirl") library(swirl) swirl() ...then follow the instructions that swirl gives. This will give you practice learning coding in R/RStudio itself, one of the best ways to learn coding.

Learning Continuity

In the event of an unexpected disruption, we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and course assessment continues to meet the principles of the University’s assessment policy. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator/director, and if disruption occurs you should refer to the university website for information about how to proceed.

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.

Similarly, research students must meet the University’s expectations of good research practice. This requires:

  • Honesty - in all aspects of research work
  • Accountability - in the conduct of research
  • Professional courtesy and fairness – in working with others
  • Good stewardship – on behalf of others
  • Transparency – of research process and presentation of results
  • Clarity - communication to be understandable, explainable and accessible

For more information on the University’s expectations of academic integrity, please see the Academic Conduct section of the University policy hub.
