Math20SG R Documentation
Bivariate score frequencies on two 20-items mathematics tests.
Description
The data set contains the bivariate sample frequencies of number-right scores
for two parallel 20-items mathematics tests given to a sample from a national population of
examinees. This data has been described and analized by Holland and Thayer (1989);
Von Davier et al, (2004).
Usage
data(Math20SG)
Format
A 21x21 matrix containing the bivariate sample frequencies for X (raws) and Y
(columns)
