student_status_norms_2015_dense_extended 2015 norm data densified and extended

Description

Builds on status_norms_2015 for students. Two data processing steps have been performed: 1) densification by percentile. For many grade levels, one step on the RIT scale equates to more than one percentile point. For instnace, moving from RIT 212 to 213 might be a jump from the 51st to 54th percentile. This dataframe 'densifies' the scale so that entries exist for the 52nd and 53rd percentile (mapping back to RIT 212). 2) extending norms into HS. The normative study doesn't cover all grades and subjects - in 2011, comparatively few HS students took MAP. Rather than return nothing at all for, say, 12th grade Reading, this data frame extends the norms from the previous grade where data exists. This is an imperfect approximation, to be sure, but is at least directionally accurate.
