The pisa data frame consists of 340 rows and 5 columns, representing the response patterns of the students to the test items. Each number, an integer, 1 or 0, encodes a correct or incorrect response, respectively.


The dataset pisa was obtained after dichotomizing the original multiple-choice or open format test data. Wording of the test items used in the assessment is not known (not available publicly).
