PHPS41150 Introduction to Biostatistics

Academic Year 2021/2022

A module covering essential and fundamental principles of statistics as applied in biology, medicine, and related fields.

The use of data to describe and infer properties of biological, clinical, and other human characteristics is increasingly important not only for academic research, but in most professional settings.

This module will introduce the student to the quantification of human characteristics, and how to best describe them using numerical summaries, and visually. We will also provide an overview of the principles of statistical inference - drawing conclusions from data and understanding the uncertainty inherent in samples of human participants. The student will also learn how to choose and use simple statistical models of data collected on samples, on groups of participants, and on serial measurements over time.

The practical use of appropriate statistical software will be taught in parallel to the more theoretical aspects of the material.

Learning Outcomes:

Upon completion of this module, students should be able to:

Understand and choose basic statistical analyses, including descriptive statistics, chi square and t tests, ANOVA models, correlation and simple linear regression, and selected non-parametric tests.

How to report findings in accordance with best practice.

How to correctly interpret and critique the results of numerical analyses of biological, medical or related data.

Indicative Module Content:

- Data and descriptive statistics
- The Normal distribution
- Comparing means and proportions between groups: t tests and chi-square tests
- Comparing many means: between-subjects ANOVA, within-subjects ANOVA, mixed ANOVA
- Correlation

Approaches to Teaching and Learning:
This module adopts a flexible, modular and problem-based approach to learning statistics.

Each week's session begins with a lecture covering the rationale, theory and mechanism for a particular statistical method or approach. Each lecture is accompanied by interactive sessions, with questions encouraged from the class, and with clear step-by-step examples where there is any mathematics involved.

Further weekly learning continues with practical computer exercises, familiarising the student with a software package, how to interpret the output, and report it correctly. Further exercise sheets for practice are provided.

Feedback Strategy/Strategies

• Feedback individually to students, on an activity or draft prior to summative assessment
• Feedback individually to students, post-assessment
• Group/class feedback, post-assessment

How will my Feedback be Delivered?

Feedback on weekly formative (not graded) exercises will be given on request or automatically by the VLE, in advance of the Computer Lab assessment. Feedback on the computer lab assessment will be given individually to students through the VLE. General feedback will be given to the full class through the VLE.
