VARIABLE LEVEL Q1 Q2 (ORDINAL).
*Perhaps even interval.
NUMERIC MyScore (f3.1).
*using MEAN to get a summative score with the same meaning as the response
scale.
COMPUTE MYScore=Mean.2(Q1 to Q2).
FREQUENCIES VARIABLES = Q1 Q2 MyScore /STATISTICS =ALL.
NUMERIC NewVar (F2).
RECODE MyScore(Missing=Copy)(4.0 THRU HI =2)(1 THRU 3.9999 =1)(ELSE = -1)
INTO NewVar.
VALUE LABELS NewVar
    -1 'Oops weird result'
    1 'Below Median'
    2 'At or above Median'.
MISSING VALUES NewVar (LO THRU -1).
CROSSTABS TABLES = MyScore BY NewVar.
