What you'll learn

  • Develop a reliable and versatile data analysis framework
  • Visualise your data with publication-ready figures
  • Master general linear models: regression, ANOVA, etc.
  • Refresh your statistical knowledge in a visual, intuitive way
  • Learn and apply the principles of hypothesis testing and model selection
  • Introduction to generalised linear models and to non-linear modelling

Requirements

  • No programming experience needed. You'll learn how to use R from absolute 0.
  • You should be familiar with statistical concepts covered in any introductory statistics course, such as: Normal distribution, model parameters, variance, standard deviation, standard error, F-test, p-value.

Description

This course is aimed at those that already have a theoretical understanding of statistical concepts and want to learn the practical side of data analysis.

Learning how to analyse data can be a daunting test. Applying the statistical knowledge learned from books to real-world scenarios can be challenging, and it's often made harder by seemingly complicated data analysis softwares.

This course will help you to develop a reliable data analysis pipeline, creating a solid basis that will make it easy for you to further your data analysis skills throughout your career.

We will use R, a free, state-of-the-art software environment for modelling, data handling, data analysis, and data visualisation.

We will start from installing R and taking baby steps to become familiar with the R programming language. We will then learn how to load data in R, how to visualise them with publication-level quality graphs, and how to analyse them.

I will provide you with the scripts that I use throughout the course, so that you can easily use them and adapt them to your own research objectives.

We will learn R one small step at a time, starting from absolute zero:

· how to enter data in R

· how to visualise data using function plot() and package ggplot2

· how to fit, interpret, and evaluate general linear models for a variety of study designs, including t test, ANOVA, regression, ANCOVA, and multiple regression scenarios

· how to fit polynomial regression

· an introduction to user-defined non-linear models

· an introduction to generalised linear models for non-normally distributed data (case study: count data)

· optimal data organisation and "data wrangling" - merging, subsetting, and summarising data

Who this course is for:

  • Junior researchers moving their first steps into practical research in natural sciences, biology, medicine, etc.

I am a quantitative ecologist (PhD) with a decade's worth of experience with performing and teaching data visualisation, data analysis, and modelling.

My expertise includes experimental design, general linear models, generalised linear models, mixed-effect models, non-linear models, multivariate statistics, and more. I do all my statistics, modelling, graphs, and data handling using the R software environment.

I have been involved in research on a variety of topics including population dynamics, community ecology, biodiversity, evolution and coevolution, biogeography, and spatial ecology, and my research has been published on international, peer-reviewed scientific journals. I like to translate the beauty of nature in quantitative terms, and to give data a voice.
