This function scores TIMSS data.
For multiple choice items, correct answers are assigned 1 point, and incorrect answers are assigned 0 points.
For constructed response items, correct answers are assigned 2 points, partially correct answers are assigned 1 point,
and incorrect answers are assigned 0 points. For both types of items, "NOT REACHED" and "OMITTED OR INVALID" are assigned 0 points.
these defaults can be changed by modifying the scoreDict
columns pointMult
and pointConst
, respectively.
