Which would you prefer: you are a student and receive a B (85) on an exam with a reliability of .67; or you are a student and receive a B (85) on an exam with a reliability of .87. Explain.
Homework Answers
Receiving a B (85) on an exam with a reliability of .67 will be preferable as the reliability is lower than the other which makes it possible that if practiced or attempted again it can probably help to score more on that exam. While the other exam has more reliability which means the test scores on that exam are equally likely to be same and has higher reliability.

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.
