ENVB40370 Data Analyses & Interpretation (On-line)

Academic Year 2022/2023

This module aims to equip you with the skills to professionally synthesize and communicate technical information in the field of biology and environmental science. The module blends online lessons, computer practicals and self-test problem sheets.

Topics covered include the reporting of data, data management, statistical modelling, design and analysis of biological and environmental experiments, hypothesis testing and the use of the R statistical software.

For this module you will require access to a computer that will run the R statistical software (available for Windows, Mac or Linux operating systems at https://www.r-project.org/) and RStudio (freely available at https://www.rstudio.com/products/rstudio/#Desktop)
