Onderzoeksmethoden

Dear students, dear visitors,

Welcome to the course site of Data Science! Data Science is a learning trajectory which is taught within the second year of the Bachelor Biomedical Sciences, Utrecht University. It includes modules on Intro R and statistics within the course ‘Onderzoeksmethoden’.

Within the Biomedical Sciences, working with big data sets becomes more and more important. Therefore, the knowledge and skills how to handle data sets and how to perform statistical analyses is an important part of biomedical education.

Following the different COOs (computer modules), you will install R and Rstudio and get acquainted with the basics of programming in R, after which you will use the programming to perform statistical analyses.

• COO 1 focuses on installing R and Rstudio, using R as a calculator, and the various objects that can be made and used in R.
• In COO 2, you will learn how to import data, how to select data, how to sort and order data, and lastly how to handle missing values.
• In COO 3, the main focus is on visualization of data with R.
• In COO 4, you will learn about descriptive statistics in R.

When the basics in R are covered, you will be introduced into different types of statistical analyses in R:

• In WC statistiek Thema 1, you’ll learn about the 95% confidence interval.
  
• In WC statistiek Thema 2, linear regression and prediction will be taught.
  
• In WC statistiek Thema 3, the topic of the students’ t-test will be discussed.

Learning R can be difficult in the beginning, but also very exciting when you keep trying and succeed.

Good luck!

On behalf of all involved teachers,

John Meeuwsen
