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.
Both dplyr
and ggplot2
libraries are loaded and world_happiness
is available.
