Many studies confirm the relationship between attendance and grades and the one referenced below is no exception. The course where the data reported in this study were collected was multiple discussion sections of a larger course. In these discussion sections attendance and participation counted for 10 percent of the total grade, 5 percent for each. Another 10 percent of the grade was determined by regular quizzes also given during the discussion sections. Findings were consistent across all sections: as absences increased, grades decreased.
