What is the median in NumPy?

How do I calculate the median of a list of numbers using NumPy?

You can use the numpy.median() function. Just pass your list or array to it.

Can you show me an example?

Sure! Here's a simple example:

import numpy as np

data = [1, 3, 3, 6, 7, 8, 9]
median = np.median(data)
print(median)  # Output will be 6

What if the list has an even number of elements?

In that case, NumPy will return the average of the two middle numbers. For example:

data = [1, 2, 3, 4]
median = np.median(data)
print(median)  # Output will be 2.5

Can I calculate the median of a 2D array?

Yes! You can specify the axis parameter. For example:

array = np.array([[1, 2, 3], [4, 5, 6]])
median = np.median(array, axis=0)
print(median)  # Output will be [2.5 3.5 4.5]
