Document Summary
As part of a research project, a student explored the impact of using electronic devices (like laptops, smartphones, etc. ) before bed on sleep. The student collected data on the amount of screentime" (i. e. time on an electronic device) before going to bed, and subsequent duration of sleep. The student also identified the evening of the week (e. g. monday) on which they recorded these values for each participant in their study. The data collected for duration of sleep (in number of hours) across weekdays (from the start of the week on sunday through end of the work week on thursday) are summarized below. The distribution of number of hours slept on sunday is likely right skewed. The distribution of number of hours slept on thursday has the largest range. The median number of hours slept increases as the week progresses from start to end. The 25th percentile for number of hours slept on sunday is the highest of all the days.
