Maddi Payan and Vikram Murugan-3rd Period
Parts of the Experiment
Independent Variable: Grade level (Last years freshmen or juniors).
Experimental Group: Last years freshmen and juniors who took at least two AP classes.
Two factors held constant: One is the number of AP classes required and the second is the grade level.
Last year the freshmen had only 1 - 5 hours of homework everyday, while the juniors had 5 - 7.5 hours of homework. This shows that the maximum number of hours of homework a freshmen did in this selected group is the same as the minimum number of hours of homework that a junior did. When comparing the average number of hours of homework, the freshmen got 2.8 hours of homework, while the juniors got an average of 6.1 hours of homework. The average clearly shows that an average freshman did about 3.3 hours of homework less than the average junior. When including standard error of the mean, the error bars ranged from 2.4 - 3.4 hours for freshmen and 5.7 - 6 hours for juniors. Since they did not have any numbers in common they were statistically different.
The reason our data pointed this way was because juniors take harder or more rigorous courses than freshmen do. Juniors usually take at least 3 AP courses while freshmen normally only take one. Due to the multitude of AP courses, juniors tend to do more hours of homework than the amount freshmen do
