Sources of Inaccuracies
With the completion of this lab, realization of many errors started appearing. One problem is that the people questioned had to in a way predict or try to recall their information. Some gave their hours of sleep per day from the past year, where they were either freshmen or juniors. Others gave predictions of this upcoming year. Many most likely gave their hours of sleep per day from the first couple weeks of school, which wouldn’t be very accurate since the workload from classes had not completely started.
