# What can't correlation measure?

While the correlation coefficient is a convenient way to quantify the strength of a relationship between two variables, it's far from perfect. In this exercise, you'll explore one of the caveats of the correlation coefficient by examining the relationship between a country's GDP per capita (`gdp_per_cap`

) and happiness score.

Both `dplyr`

and `ggplot2`

are loaded and `world_happiness`

is available.

Instructions 1/3

**undefined XP**

- Create a scatterplot showing the relationship between
`gdp_per_cap`

(on the x-axis) and`life_exp`

(on the y-axis).
