Age is a quantitative variable because it involves numerical values. It is also continuous because it can take any value within a certain range (e.g. 20.5 years old). Lastly, it is a ratio variable because it has a true zero point (0 years old) and the ratios between values are meaningful (e.g. someone who is 40 is twice as old as someone who is 20).
