Simpson's paradox

Público14 September 2026 at 00:05

The article refers to Simpson's paradox in the context of PISA 2025 data. Simpson's paradox is a statistical phenomenon in which a trend that appears in grouped data disappears or reverses when the data are analyzed in separate subgroups.

The text indicates that the PISA 2025 data reveal that, in the use of artificial intelligence in education, the determining factor is not the quantity of use by students, but rather the way in which this technology is used.

The article is presented as an opinion piece by João Marôco, whose name suggests he is a specialist in statistics or education, given the nature of the topic discussed.

However, the provided text consists only of the title and author identification, without containing the body of the article with the complete analysis necessary for a detailed summarization.

Why this matters

This analysis is of interest to educators and policymakers in Portugal and the Portuguese-speaking world, as it demonstrates that simply investing in more technology does not automatically improve student outcomes — teachers need training and clear guidelines on how to integrate AI in a pedagogically effective manner in the learning process.
