Description

Data from the PISA2012lite package (European countries only).

Usage

data(pisa2012)

Details

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 with the seed 123. Then only European countries were chosen.

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)
