The age of the child is a significant confounding variable that influences both height and reading ability.

Elementary school consists of children aged approximately between age 5 to 12. Children between the ages of 5 and 12 vary considerably in their height. Similarly a child aged 5 will typically have a lower reading ability compared to a child aged 12 due to the latter possessing more advanced language skills and receiving more reading practice.
