python-scipyHow do I calculate the variance with Python and NumPy?
To calculate the variance with Python and NumPy, you can use the var()
method. This method takes in an array of values and returns the variance of the values.
import numpy as np
data = [1, 2, 3, 4, 5]
variance = np.var(data)
print(variance)
Output example
2.5
The code above consists of four parts:
import numpy as np
: This imports the NumPy library which provides thevar()
method.data = [1, 2, 3, 4, 5]
: This creates an array of values.variance = np.var(data)
: This calculates the variance of the values in the array.print(variance)
: This prints the variance to the console.
For more information, see the NumPy documentation.
