Science is fundamentally about testing ideas, not collecting facts. But how do we test ideas? We do so by analysing numbers to reveal patterns, and then by designing experiments to exclude competing ideas that might explain what causes these patterns. In this course, you will discover how to design experiments and analyse data. You’ll then be equipped to critically assess scientific claims that you hear in the media. Think about how much of the news is about alleged medical breakthroughs, causes of health problems, and claims that one economic policy is better than another. We want to help you to sift out fake news, identify misleading ways to describe data and allow you to assess the importance of different factors in explaining the patterns we see in the world. This is a core life skill. And, naturally, if you take this course you’ll be better equipped to take the path to becoming a biologist yourself.

 

This course will explore the ways biologists design experiments, generate data and assess evidence using a variety of statistical techniques. We will discuss the value of different scientific approaches, including hypothesis-driven experiments and exploration of large-scale data generation–such as genome and transcriptome sequencing projects. We’ll consider examples from microbial, animal and plant biology, and you will carry out exercises to develop and test hypotheses, and critically interpret the results. You will have the opportunity to participate in all stages of a biological experiment. This will include the conception and design of a study, laboratory work, analysis of the data, drawing conclusions, writing the report and engaging graphical ways to present your findings. The R programming language will be taught and used throughout the course. Students will be required to use their laptop computers.

Honours Pathway Option (HPO): This course offers optional HPO and ASE add-ons for undergraduate students.

HPO and ASE students will be required to demonstrate greater depth of understanding of the content of the course. They will undertake an independent or group inquiry-based research project. Students will be required to write and present report from the project. The project will include:

• literature review,
• analysis and critical evaluation of research data, and
• presentations of the research.

The fields of research will include:

• genetics and genomics,
• epigenetics,
• biostatistics.

Either add-on will count for 20% of the mark for enrolled students. In this case the regular course assessments (Assignments x3, Lab report, Mid-term quiz and Final Exam) will be scaled down to 80%.

Students participation in these options must be approved by the course convener. Students should contact the course convener regarding availability and specific requirements before or immediately after the course start.

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

1. Understand when to apply different experimental approaches in biology and how to use experimental models.
2. Proficiently apply R programming skills in RStudio environment for experimental data analysis and visualization.
