The strangely similar patterns of attendance and age

It's been a while since my last post.  This analysis is a little bit of a teaser and raises more questions than it answers.  But sometimes those are the best ones.

This analysis was done in response to a query about student retention.  That generated the following chart.  You will notice a drop off in the hours attended at the higher end of the ABE/ASE range.  The ESL attendance seems to be fairly steady across all levels.


So Sandy from NYSED suggested looking at the attendance by age.  This generates the following pattern.  It is very interesting that both charts look very similar to each other.  Does it follow that age predicts attendance?
