This Student to Teacher Ratio dataset originates from R for Data Science's Tidy Tuesday weekly event for May 7, 2019. It describes student to teacher ratios by country, year, and educational level.

Questions for consideration:

• How does educational level correlate to ratio?
• Which countries have the largest disparity of ratios across different educational levels?
• Which countries have improved their ratios the most over time?

Country and educational level are categorical. Ratio is quantitative.
