At the end of the module:
- Students are able to carry out simple and multiple regression analyses on a given data set using R for statistics
- Students can interpret all standard output of simple regression and multiple regression using R for statistics (including ANOVA table and Parameter estimates table).
- Students know how to code categorical variables into dummy variables and carry out and interpret F-tests.
- Students are familiar with the basic concepts of inference: confidence intervals, standard errors, t-tests and F-tests, null hypothesis testing and p-values, and know the distinction between the sample data and the population that one wants to make inferences about.
- Students know how to check the assumptions of linear regression and are able to use nonparametric alternatives in case assumptions are not met (Kruskal-Wallis, Spearman and Kendall).
- Students know how to present data analysis results in a report following APA guidelines.

This Research Methods study unit is part of the module Social Behaviour (202000325). The study unit provides a foundation for an essential ingredient of conducting research: quantitative data analysis. It introduces the basic notions of inferential data analysis through a practice-oriented approach.
In this study unit students are introduced into the basic notions of data analysis that would allow them to make inferences about populations on the basis of a randomly sampled data set. The course uses the regression model as the basic skeleton and introduces confidence intervals, null-and-alternative hypotheses, t-tests, interactions, dummy variables, statistical power, and analysis of variance within the unifying linear model framework. In addition, it familiarizes students with the logic and implementation of non-parametric statistical analysis. The way in which these methods are to be performed are illustrated using research examples. The software used is R for statistics.
