Student stress at final exam time comes partly from the uncertainty of grades and the consequences of those grades. Can knowledge of a midterm grade be used to predict a final exam grade? A random sample of 200 BCOM students from recent years was taken and their percentage grades on assignments, midterm exam, and final exam were recorded. Let’s examine the ability of midterm and assignment grades to predict final exam grades. The data are shown here: Assignment Midterm FinalExam...
