Great job computing the variance! The last statistic will be much simpler: standard deviation.
The standard deviation is the square root of the variance. You can calculate the square root by raising the number to the one-half power.
Instructions
1.
Define a function, grades_std_deviation
, that takes one argument called variance
.
return
the result of variance ** 0.5
After the function, create a new variable called variance
and store the result of calling grades_variance(grades)
.
Finally print
the result of calling grades_std_deviation(variance)
.
