Standard Deviation:
The Standard Deviation of the population is given by the square root of Variance.
Method Name:
pstdev(data)
Method Overview:
The pstdev() function takes a sequence or an iterator containing the population data and returns the Standard Deviation of the population which is the square root of the Variance.
Exceptions:
Python raises a StatisticsError if the data passed inside the pstdev() is empty.
Python example program for finding Population Standard Deviation:
|
# import the statistics module import statistics
populationData = [126,122,130,124,121,121,125,132,137,118]
# find Population Standard Deviation populationSD = statistics.pstdev(populationData)
print("Standard Deviation of the Population is %.2f"%(populationSD))
|
Example Python program output that finds Population Standard Deviation:
|
Standard Deviation of the Population is 5.54 |
