A fictional μMCTQ dataset
Description
![[Maturing]](../help/figures/lifecycle-maturing.svg)
A fictional dataset, for testing and learning purposes, composed of
basic/measurable and computed variables of the Munich ChronoType
Questionnaire (MCTQ) micro (μ) version.
This data was created following the guidelines in Ghotbi et al. (2020), in
addition to the guidelines in Roenneberg, Wirz-Justice, & Merrow (2003),
Roenneberg, Allebrandt, Merrow, & Vetter (2012), Jankowski (2017), and The
Worldwide Experimental Platform (n.d.). See the References and Details

Guidelines
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).
To learn about the sleep-corrected social jetlag, see Jankowski (2017).
If you're curious about the variable computations and want to have access to
the full questionnaire, see The Worldwide Experimental Platform (n.d.).
Data building and data wrangling
This dataset was created by randomized sampling (see
random_mctq()) and by manual insertions of special
cases. 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.
You can see the micro_mctq build and data wrangling processes
here.
Variable naming
The naming of the variables took into account the naming scheme used in MCTQ
publications, in addition to the guidelines of the tidyverse style guide.
Variable classes
The mctq package works with a set of object classes specially created to
hold time values. These classes can be found in the hms
and lubridate package.
Duration objects
If you prefer to view Duration objects as
hms objects, run
pretty_mctq(micro_mctq).
