Transforming variables

When variables have skewed distributions, they often require a transformation in order to form a linear relationship with another variable so that correlation can be computed. In this exercise, you'll perform a transformation yourself.

pandas as pd, numpy as np, matplotlib.pyplot as plt, and seaborn as sns are imported, and world_happiness is loaded.
