Eat, sleep, repeat

Now the subjects were also asked to record other activities: washing, sleeping, watching tv, etc. These can be found in the dataset daily_activities.

Use the three available performance metrics to solve the questions below.

  • processing_time() measures the time a person is active
  • idle_time() measures the time a person is idle
  • throughput_time() measures the total time between first and last reported event

  • Which of the activities uses the most time? And which the least? Show graphically after using the processing time metric.
  • What is the average duration (in hours) on which data is reported, i.e. from the first activity a person executes until the last activity of that person?
  • Not all subjects recorded their activities continuously. What is the amount of time per subject (on average, in hours) of which the activities were idle?
