Fictional datasets, for testing and learning purposes, composed of basic/measurable and computed variables of the Munich Chronotype Questionnaire (MCTQ) standard, shift, and micro versions. The *.csv files represent the raw data and *.rda files the processed data. This data was created by randomized sampling and by manual insertions of special cases. You can find it in the mctq R package. Its purpose is to demonstrate common cases and data issues that researchers may find in their MCTQ data, in addition to be a suggested data structure for MCTQ data. To learn more about the Munich Chronotype Questionnaire (MCTQ), see Roenneberg, Wirz-Justice, & Merrow (2003), Roenneberg, Allebrandt, Merrow, & Vetter (2012), Roenneberg et al. (2015), and Roenneberg, Pilz, Zerbini, & Winnebeck (2019). To know about different MCTQ versions, see Juda, Vetter, & Roenneberg (2013) and Ghotbi et al. (2020). If you're curious about the the variable computations and want to have access to the full questionnaire, see The Worldwide Experimental Platform (n.d.).
