About this module

This collection accompanies the part on exploratory data analysis in the master's module Empirical Research. The slides use the survey on milk and chocolate to show what exploring achieves and which type of question it can answer; after that one section introduces R, the next data transformation with dplyr and another data visualisation with ggplot2; further sections on describing and checking data are being written right now and will also be available from the start. At the end a self-assessment shows you where you stand.
