Introduction to Data Science

Eight Sessions – 9.30am to 1.00pm.

Dates: September to November 2022

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.

See this video for an introduction to the course, the trainers and what you will learn.

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.
