Tematika

In this course, students will have the opportunity to learn advanced data management methods in the R environment to supplement their analytical skills.

Primary focus will be on advanced level script writing, data management using the tidyverse package, writing basic custom functions, and data export and reporting. Students will primarily learn by examples from sociological, psychological, demographic and business application.

Topics – Data analysis

1.      Basic data management in R: objects, vectors, data frames.

2.      Transforming and importing data.

3.      Handling lists in R.

4.      Creating and working with matrices.

5.      Working with time-based data.

6.      Efficient script writing in base R.

7.      Introduction to writing functions in R.

8.      Introduction to the tidyverse: the basic concepts of “tidy” data. I.

9.      Introduction to the tidyverse: the basic concepts of “tidy” data. II.

10.   Advanced visualization using ggplot2.

Topics – Statistics

1.      Descriptive methods for categorical and continuous data.

2.      Hypotheses testing I.: t-tests, chi-square and correlation.

3.      Hypothesis testing II.: anova and non-parametric methods.

4.      Regression modeling: OLS linear regression.
