How can I use NumPy for statistical analysis?

You can use NumPy to perform various statistical operations like mean, median, variance, and standard deviation. Would you like to see some examples?

Yes, please show me how to calculate the mean and standard deviation.

Sure! You can calculate the mean using numpy.mean(data) and the standard deviation with numpy.std(data). Here's a quick example:

import numpy as np

data = [1, 2, 3, 4, 5]
mean = np.mean(data)
std_dev = np.std(data)
print('Mean:', mean)
print('Standard Deviation:', std_dev)

What if I have a large dataset?

NumPy handles large datasets efficiently. You can use the same functions, and they will perform well even with large arrays.
