| Abstract: |
|
In this paper we examine four statistical methods used for characterizing mathematical
test items regarding their demands of reading ability. These methods rely
on data of students’ performance on test items regarding mathematics and reading
and include the use of regression analysis, principal component analysis, and
different uses of correlation coefficients. Our investigation of these methods focuses
on aspects of validity and reliability, using data from PISA 2003 and 2006.
The results show that the method using principal component analysis has the best
properties when taking into account aspects of both validity and reliability.
