The activity of an academic statistician were divided into following six categories
teac | teaching | |
cons | consultation | |
admi | administration | |
rese | research | |
wake | other wakeful activities | |
slee | sleep |
Data show the proportions of the 24 hours devoted to each activity, recorded on each of 20 days, selected randomly from working days in alternate weeks, so as to avoid any possible carry-over effects, such as short-sleep day being compensated by make-up sleep on a succeeding day.
The six activity may be divided into two categories 'work' comprising activities 1,2,3,4: and 'leisure' comprising activities 5 and 6.
All rows sum to one.
