Abstract
As described in Chapters 5 and 6, the cognitive data in PISA are scaled with the Rasch Model and the performance of students is denoted with plausible values (PVs). For minor domains, only one scale is included in the international databases. For major domains, a combined scale and several subscales are provided. For each scale and subscale, five plausible values per student are included in the international databases. This chapter describes how to perform analyses with plausible values.
