NAEP Technical DocumentationNAEP 2002 Main Study Student Nonresponse Adjustment Factors

The final student nonresponse weighting adjustments are designated as STNRADJ_d, d = 1,...,D, where D is the total number of weighting cells. The student nonresponse adjustments were computed as follows for each nonresponse weighting cell:

where

• S_d is the set of all eligible session "A" sampled students in cell d;

• R_d is the set of all assessed session "A" students within S_d; and

• STUWGT_sk is the student base weight.
