You’ve done a great job completing this program.

We’ve created quite a few meaningful functions. Namely, we’ve created helper functions to print a list of grades, compute the sum, average, variance, and standard deviation about a set of grades.

Let’s wrap up by printing out all of the statistics.

Who needs to pay for grade calculation software when you can write your own? :)

Instructions

1.

Print out the following:

  • all of the grades
  • sum of grades
  • average grade
  • variance
  • standard deviation
