Why can't you find the "average eye color" of your class?

Is "zip code" categorical or numerical? Explain your reasoning.

You want to show how the temperature in your city changed each month this year. What data type is temperature and what graph would you use?

๐Ÿ  Take-Home Challenge โ€” Data Type Spotter!

Find a graph or chart anywhere (newspaper, website, cereal box, weather app). Bring it in or describe it next session.

โ˜ What type of data does it show? (Categorical or numerical?)
โ˜ What graph type was used?
โ˜ Was that the best graph choice? Why or why not?

My graph shows:
