Average school size here is the simple mean of every school's enrollment within a state, so each school counts once regardless of how many students it serves; it describes the size of the typical school, not the size the typical student attends. The figure also blends grade levels: elementary schools are usually smaller than high schools, so a state's average partly reflects its mix of school types as well as its settlement pattern.
