Possibly wrong instruction in python lession "exam statistics- standard deviation"


#1

if you look at the instruction 03 should be 02 and vise versa
and last instruction 04 there is no list called variance in the programe so how can you pass it as a argument.



#2

Hi why ? the instuction are on the right oder..

1 Define a function grades_std_deviation(variance).

def grades_std_deviation(variance):

2 return the result of variance ** 0.5

def grades_std_deviation(variance):
    return variance ** 0.5

3 After the function, create a new variable called variance and store the result of calling grades_variance(grades).

def grades_std_deviation(variance):
    return variance ** 0.5

variance = grades_variance(grades)

4 Finally print the result of calling grades_std_deviation(variance).

def grades_std_deviation(variance):
    return variance ** 0.5

variance = grades_variance(grades)
print grades_std_deviation(variance)
