How do I calculate quantiles using NumPy in Python?

You can use the numpy.quantile() function to calculate quantiles. Just pass your array and the desired quantile.

Can you show me an example?

Sure! Here's a simple example:

import numpy as np

data = [1, 2, 3, 4, 5]
quantile_25 = np.quantile(data, 0.25)
quantile_50 = np.quantile(data, 0.5)
quantile_75 = np.quantile(data, 0.75)
print(quantile_25, quantile_50, quantile_75)

This will give you the 25th, 50th, and 75th percentiles.

What if I have a large dataset?

The numpy.quantile() function works efficiently with large datasets as well. Just ensure your data is in a NumPy array format for optimal performance.

Are there any other functions for quantiles in NumPy?

Yes, you can also use numpy.percentile() if you prefer to work with percentiles instead of quantiles. The usage is similar!
