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.
