Purpose

•  

 

The purpose of our topic was to determine whether the schedule change affected the mean number of tardies per student for the first three quarters of the 2013-2014 school year.  We chose this topic because it is a much debated topic in our school right now due to the change from 7:45 to 7:20.  We wanted to see if people’s complaints that the earlier schedule would cause more tardies were valid.  Based on other studies testing early start time effects, there seemed to be negative effects of an earlier start time.  We wanted to see if this held true in our school specifically pertaining to the mean number of tardies per student.  With this year being the first year of the schedule change, people were much more interested about the effects of the schedule change.  Since most of our time is spent at the school or involved with school activities, we decided to study an issue that related to our daily school lives instead of an impersonal topic.
