WHat are the variables of this longitudinal study:

grade 9 students are surveyed about the number of hours they study. Those grade 9s are surveyed again when they're in grade 11. Would the variable be grade level and number of hours studied?

Mark M.

Many intervening variables: location, course, intellectual growth, success/failure.
