Course Overview
This workshop is designed as an introduction to statistical analysis for researchers. There is emphasis on understanding the concepts of statistical procedures (with a minimum of mathematics, although some will be discussed) and on interpreting computer output. It is designed to help you, the researcher. It is helpful if you have done an undergraduate statistics subject, although this workshop can serve as a first introduction or a refresher. The theory behind the statistical procedures will, in general, not be discussed.
A range of statistical analyses will be discussed in the workshop, as described in the outline below. We will talk through examples of all analysis types and will demonstrate how to carry them out in R. Equal emphasis will also be put on interpreting the output of these analyses. There will be plenty of practical work.

2025 - Fundamentals of Regression in R
11 - 13 February
Course Overview
This course provides a comprehensive hands-on introduction to regression analysis techniques The course content is designed for researchers with some prior knowledge of basic statistical testing, such as t-tests, p-values, confidence intervals and simple linear regression. The primary focus is on developing a conceptual understanding of regression models through numerous examples. There will be a strong emphasis on practical implementation in R, and interpretation of output. Approximately half the time will be dedicated to practical hands-on sessions.
The core content starts from linear models with more than one variable, enabling research questions like "What is the effect of this treatment/intervention after adjusting for confounding variables?" or "What is the relationship between two variables while controlling for other factors?" We then cover interactions between variables in linear models, enabling research questions like: "How does the effect of the treatment depend on some other variable? Is the treatment effect different between groups?" and "How is the relationship between two variables modified by some other variable?"
Fundamental regression concepts and skills that arise in regression, like multicollinearity, multiple testing, model selection, generalising the linear model to data that is non-normal (e.g., binary response and count data), are all covered in this course. By the end of this course, you will have a foundation in regression modelling techniques with the practical experience in R needed for more advanced regression methods like mixed models, longitudinal data analysis, survival analysis, meta-analysis, generalised additive models, multivariate analysis, ordinal and multinomial regression, spatial regression and other extensions.

2024 - Multivariate Statistics Using R
8 August
Course Overview
This workshop is designed as an introduction to multivariate statistics in a model based framework. We aim to move beyond analysing a single response variable to visualising and analysing a collection of correlated response variables. Methods available to you depend on the number of responses relative to your sample size; and like in univariate regression we also need to think about the response variable type (binary, count etc). There is emphasis on understanding the concepts of statistical procedures (with a minimum of mathematics, although some will be discussed) and on interpreting computer output. It is designed to help you, the researcher. There will be plenty of practical work.
You will be expected to understand the basics of univariate regression including concepts like choosing a “family” (e.g. Binomial, Negative Binomial), interpreting model coefficients and checking assumptions as well as have basic R skills. Topics to consider refreshing include linear models, generalised linear models, and linear mixed models.

2024 - Intermediate R
24-25 July
Course Overview
In this course, we teach students techniques for scaling up their analyses. How do you get R to repeat tasks in an efficient way? This general skill is needed in diverse contexts, such as processing lots of files (e.g. from imaging or surveys), working with large datasets, or simulations (statistical or individual-based). In these circumstances, you'll often find yourself having to repeat the same thing over and over and it's good to learn how to get R to do this in an organised and efficient manner. We'll introduce a series of powerful tools, all which take a bit of instruction and practice to master.
Course Outline
This course will cover topics including:
Advanced data processing with tidyverse, including dplyr, joins, nests
Functional programming with purrr
For loops
Writing your own functions
Presenters and Expertise: A/Professor Daniel Falster and A/Professor Will Cornwell, School of Biological, Earth & Environmental Sciences (BEES)
Course Requirements: Own laptop with R (4.2 or newer) and Rstudio installed.
Course Prerequisites: Intermediate R users (have been using R for at least 6 months, comfortable loading data, using basic ggplot and dplyr)
Dates: Wednesday 24 and Thursday 25 July 2024
Duration: 9.00am - 4.00pm, each day
Location: This course will be delivered in person only!
You will receive a certificate of completion for the course.
2024 - Mixed Models using R
1-2 July
Course Overview
Simple statistical methods (t-tests, chi-square tests, linear models/regression) assume independence of observations and cannot be used when dependence is present in the sample. Mixed models are extensions of linear models to dependent data. Common reasons for dependence are
Clustering e.g. multiple patients per hospital, multiple plants per site, multiple measurements on the same individual
Time and Space - measurements taken close in time and space are more similar (dependent)
In this course we will teach mixed models as a straightforward extension of (generalised) linear models. The course will include lectures and practical sessions, and explain how to fit, check, interpret and communicate results from mixed models.
Accessibility

2020 - Text Analytics in Python (Advanced)
8 and 9 September
Course Overview
More than 70% of the data on the internet is unstructured. Among them, text is the most common form that appears in almost all data sources. For example, text data such as emails, online reviews, tweets, news and reports hold valuable information and insight for most research and applications. Text analytics, usually involving techniques from text mining or natural language processing (NLP), can automatically uncover patterns and extract meaning/context from these unstructured texts.
This course assumes that you have basic Python programming knowledge, or have previously attended "Introduction to Python for Data Science" from Stats Central. This course will provide you the foundation to process and analyze text.
In this course, we will cover some useful Python features and libraries for text processing and analysis. We will touch on some advanced topics such as sentiment analysis, text classification, and/or topic extraction.

Location: Online
2020 - Study Design
19 May
Course Overview
Good study design is crucial for answering your research questions. No amount of post processing or statistical expertise can compensate for poor or inadequate study design. In this course you will lean the basic concepts of study design including how to;
Randomize, so that your sample can be used make inferences about the real world (the population).
Implement appropriate controls and manipulation to infer causation.
Determine adequate sample size.
We will then move on to advanced concepts, which will focus on how blocking and stratification can reduce variability and improve power (the ability to answer your research question) using a smaller sample size (hence less resources).
Practical Component
How to randomise – Random allocation of subjects to treatments and random sampling
Simple power analysis – How much data do we need to answer the question of interest?
We will use free online tools and the software packages, either Excel and G*Power; or R (optional).
Course Requirement: You will need a computer with Excel (or equivalent) and G*Power installed and access to the course.
