PSY9510 ¨C Introduction to Statistics with R

Course content

R is a free and open-source programing language and that is very popular for data manipulation, statistical analyses, and graphics. This course provides a broad introduction to programming fundamentals with a focus on how R can be used for data management, descriptive statistics, graphics, statistical analysis and reproducible research.

Learning outcome

The course walks the participants through the basics of R programming and provides skills for organizing analysis projects, R code as well as skills for data management (RStudio Projects) and reproducible statistical analysis (Quarto). The course starts using base R and progresses into various functions from the tidyverse package. It also provides a thorough guide to the grammar of graphics for developing publication-ready figures via the ggplot2 package.

The learning objectives of the course are as follows:

• Become familiar with R and the RStudio environment.
• Understand datatypes and their characteristics.
• Manipulate different data structures in R.
• Perform data cleaning and data management using base R and the tidyverse package.
• Carry out data quality checks.
• Write and organize R syntax and implement reproducible analyses within RStudio.
• Produce descriptive statistics in R.
• Run basic statistical analyses.
• Produce publication-ready graphics with ggplot2 package.

Emphasis is placed on the practical mastery of the tools mostly used to manipulate behavioral data. Students can use the acquired skills while working on their thesis and other reproducible research projects. An important goal of this course is to foster students¡¯ analytical independence in R so that they are capable of developing their skills in the future.

Recommended previous knowledge

There are no formal perquisites for taking this course. Students are expected to have basic understanding of statistics (e.g., linear regression), but no previous knowledge of programming or R language is required. Only the willingness to learn to write code is required.

Teaching

The course duration is equivalent of 24 seminars hours and is offered each semester. Seminars are composed of mini-lectures and practical computer exercises.
