Question 891843: A student's parents promise to pay for next semester's tuition if an "A" average is earned in Math. With examination grades of 97%, 97% 75%, 70% and 55%, the student reports that an "A" average has been earned. Which measure of central tendency is the student reporting as the average. How is this student misrepresenting the course performance with statistics?

The student is reporting the mode -- 97% occurs twice while the rest occur only once.
The median (middle number) is 75%
The mean is (97+97+75+70+55)/5, or 78.8%
.
Hopefully the parents are wise to him ;-)
