Exercise

Attrition rates by recruiting source

Another quality of hire metric you can consider is the attrition rate, or how often hires leave the company. Determine which recruiting channels have the highest and lowest attrition rates.

In the last exercise, the output was a data frame with the recruiting channels and the average quota attainment. It would have been easier to tell which channel had the highest-performing employees if it were sorted with arrange().
