Fundamentals of Data Science for Health and Care Using R

Summary of the course

In this course we will introduce the basic ideas of Data Science and we will implement them using the R programming language. We will use the Tidyverse, which is a collection of R packages that facilitate data import, manipulation, encoding, exploration and visualisation.

Learning outcomes

  • To understand basic concepts of data science and how to implement them in R using the Tidyverse.
  • To learn how to extract and communicate insights retrieved through data analysis.
