The Difference in Correlation Between Attendance and Grade Point Average Throughout Secondary Education

Overview

This project was designed to determine if there is a difference in the relationship between attendance and grade point average (GPA) from middle school to high school. T o test this, the percentage of school attended and a grade point average for 800 students within the Fairbanks North Star Borough School District ranging from grades 7 through 12 were provided by the school district. Confidence intervals for the slope of the regression line for middle school and high school were then calculated. Middle school had a slope of 4.3975, an Rsquared value of 0.3596, and a 95% confidence interval of (2.9538, 5.8413). High school had a slope of 4.6369, an R squared value of 0.3384, and a 95% confidence interval of (2.9088, 6.3650). Through this, no statistically significant difference in the relationship between attendance and GPA between middle school and high school was found. The confidence intervals for individual grade levels were also calculated and there was still no statistically significant difference for the relationship between GPA and attendance. This leads to the conclusion that there is no greater detriment to missing time in different grade levels throughout one’s secondary education.
