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.

7 1) Research has shown that activating negative stereotypes can have an effect on performance of complex tasks (Jones & 8 Joans, 1972). To test this phenomenon, a sample of n-25 female college students was given a mental rotation task at noon on one day and s again at noon on the following day. On the first day, the students simply completed the task. However, on the second day, a negative stereotype was activated 10 prior to the task by...
