The National Statistics Competition is a competition that can train students to provide appropriate solutions to existing problems based on careful data analysis. It is hoped that the output of this competition will be for students to have broad insight, be quick and precise in solving a problem and be able to convey the results well to the wider community. In 2020, this competition was called the National Statistics Competition (KSN). In the preliminary round, participants were given 50 multiple choice questions with a correct answer worth +4, a wrong answer -1, and a non-answer worth 0. In this round, the system was set so that you could not return to the previous question and the total processing time was 2 hours. In this round, 53 students were selected with the highest national scores to advance to the semifinal round, Adi Setiawan, a student from the YSU Statistics Study Program Class of 2018, was one of them. In the semifinal round, participants were given a problem and were required to solve it within 6 hours and put the results into a paper. In that round, Adi wrote the title "Modeling Poverty Cases in Indonesia Using Truncated Spline Nonparametric Regression", but still couldn't make it to the final.
