Here is the stats:
Sample size = 50, mean of sample size is 1.137, standard deviation: 1.029
My objective is to determine the coorelation between homework completed and grades students in my stats class.
Grades(number of students):
A=21, B=16, C=9, D=3, F=1; median: B
Times study per week:
0 times= 18 students, 1 times=14 students, 2 times=13 studetnts, everyday= 5 students; median: Once a week.

You got me floored on this. First, what is your observation for which you have a mean and s.d.?
Next, you seem to be switching to some discrete interval analysis, for which means and s.d. is not appropriate. What gives?

There is no way of knowing the sample size N from the information given.
