7variance"grades_variance seems to be missing!"


#1

help me!



#2

The error is line 25.

Try doing this

total_variance = variance / len(scores)

Also your indentation is a bit off your return statement should be at the same indent level as your for statement


#3

I have solved it.
I wrote grade_variance wrongly instead of grades_variance which the system asks me to do.


#4

Oh cool :slight_smile:
