Calculating Mean and Median Values with Python

You're already familiar with the mean and median, but now let's calculate them using Python. To do this, we need to import the NumPy library with the np alias.

Let's begin by importing the library:

We will use the .mean() and .median() functions to calculate the mean and median values, respectively. Here's a code example, feel free to modify the columns and observe the results:


              12345678910111213
            
# Import library
import numpy as np
import pandas as pd

df = pd.read_csv('https://codefinity-content-media.s3.eu-west-1.amazonaws.com/a849660e-ddfa-4033-80a6-94a1b7772e23/update/ds_salaries_statistics', index_col = 0)

# Calculate the mean value
mean = np.mean(df['salary_in_usd'])
# Calculate the median value
median = np.median(df['salary_in_usd'])

print('The mean value is', mean)
print('The median value is', median)
