“Average” in the top six rows for wake, wake + 30 minutes, 1000 h, 1200 h, 1800 h and bedtime refers to the percentage of people whose average time difference between requested and actual sampling time falls within a given time range across the three days.
The “average” numbers for the rows labeled “Day 1, Day 2, and Day 3” refers to the average delay in minutes across the six samples for each individual day.
Note: The numbers in parentheses represent the range for the percentage of people who fall within a certain time range for each sample for the three days.
