Applied Mathematics and Digital Technologies students develop analysis to measure the happiness of a nation

As part of the Applied Project for the bachelor’s degree program in Applied Mathematics and Digital Technologies, students Carolina Percina and Rinali Pabari conducted an analysis to determine which sociodemographic characteristics most accurately predict a population’s happiness.

To understand which characteristics had the greatest influence on happiness indices, refuting the premise of the impact of money, the students carried out a statistical analysis. As Carolina Percina mentions

"There was always the stigma that happiness was predicted by money, that is, by gross domestic product, and that's it, this is wrong because there are several aspects that influence much more."

Throughout the project, the students had the opportunity to put into practice mathematical knowledge acquired throughout their degree, such as the use of a multiple linear regression model. For the team, mathematics and statistics are precise and reliable methods for analysis.

"We applied two different methods than those that already exist. Instead of using machine learning models, which may not be 100% accurate, we tried to use a more robust method, through statistics and mathematics."

Projects like this reflect Iscte-Sintra's focus on learning oriented to real application, allowing students to develop skills in preparing studies and analyzes that contribute significantly to society.
