Aim

The service aims to improve the statistical content of research carried out by members of the University. Researchers from all disciplines may use the Centre. Priority is currently given to staff members and postgraduate students undertaking research for Doctor of Philosophy or Masters' degrees. The centre does not provide consulting support for honours students.

How we can help

It is important that University researchers consult the Centre at the beginning of their investigation, so that their research will include clear research hypotheses and well-designed data collection processes as these are basic to any analysis.

The assistance provided by the Statistical Consulting Centre includes advice on:

  • The planning of experiments,
  • Designing questionnaires,
  • Data collection,
  • Data entry and management,
  • Statistical analyses,
  • The presentation of results.

Planning the data gathering process is crucial to research, and consulting with the Statistical Consulting Centre at this stage will reap the most reward.

Currently the Statistical Consulting Centre provides each University researcher with a free initial consultation. Up to ten hours per calendar year of consulting time maybe provided without charge if research funding is not available. When researchers require more consulting time, or receive external funding, a service charge is necessary.

The Statistical Consulting Centre can arrange for later data entry and statistical analyses for those who wish to pay for these services rather than do the work themselves.

Course outline

Mixed modelling is central to modern statistical analysis and is often considered the go-to analysis for large health, social science, ecological, and biological data sets, particularly when there are repeated measurements for each subject or when there is clustering or multiple-levels apparent in the data. Mixed models can also be applied to longitudinal data with missing observations, a common hinderance to fitting ANOVA models. Able to be used across many data situations, mixed models are a form of regression analysis that are essential for any pioneering data analyst to have available to them.

This introductory in-person workshop covers the basics of building linear statistical models, covering standard regression analysis, interpreting categorical predictors and using interaction terms. We introduce exactly what are mixed models, what data is suited to mixed models, how to apply mixed models in R, and how to properly interpret the results. We will also cover the basics of using R and RStudio and give an overview of the tidyverse functions that can help get your data in the correct form for analysis. No prior knowledge of R is necessary. We will also show you how to create appealing data visualisations for clustered data using ggplot2.

This is a unique entry level workshop specifically designed to teach the basics of data science and machine learning for the health and social sciences.

Course outline

The workshop will cover the most in demand data science and machine learning methods for both supervised (regression, classification and regression trees, neural nets and support vector machines) and unsupervised learning (clustering). Participants will learn how to choose the appropriate method, and how to analyse and interpret the results using RStudio. No prior knowledge of RStudio is necessary, RStudio will be introduced as part of the course.
