data(pisa2012)
The original dataset (Program for International Student Assesment, http://www.oecd.org/pisa/) contains information on students'
performance on various cognitive tests expressed with so-called plausible values measured in three fields: Mathematics (PV1MATH),
Science (PV1SCIE) and Reading (PV1READ).
pisa2012 is a reweighted version of the PISA2012lite data. The weighting was performed using the W_FSTUWT variable.
The variables are as follows (original column names from the PISA2012lite package are given in brackets):
math – student's performance in Mathematics (originally: PV1MATH)
reading – student's performance in Reading (originally: PV1READ)
science – student's performance in Science (originally: PV1SCIE)
country – student's country (originally: CNT)
