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:

We were unable to transcribe this imageThese scores would be easier to visualize and interpret if they were graphed as a histogram. To do that, we first need to group them into class intervals and present them as a frequency distribution of grouped scores Table 2 divides the range of these 25 schools' academic performance into ten intervals.
