How to calculate standard deviation in python

Posted On April 6, 2023

To calculate the standard deviation in Python, you can use the statistics module, which provides a function called stdev() for this purpose. Here’s an example of how you can use this function:

import statistics as stats

data = [1, 2, 3, 4, 5]
stdev = stats.stdev(data)
print(stdev)

This will output the standard deviation of the data list, which is 1.5811388300841898 in this case.

If you don’t have the statistics module, you can calculate the standard deviation using the numpy library. Here’s an example:

import numpy as np

data = [1, 2, 3, 4, 5]
stdev = np.std(data)
print(stdev)

This will give you the same result as before.
