    There is a correlation. Is it positive or negative?

  2. Does there appear to be a connection between height and spelling ability?


  3. Does greater height cause better spelling ability?


  4. What other factors could create the correlation you see?

    People grow as they get older, they also learn as they get older. Does height affect spelling? No. But something might affect both factors.
