The National Statistics Competition (NSC) is a competition to train students in solving statistical problems broadly and analyzing data carefully so that they can provide the right solution for a given problem. In this competition, students are required to have high intellect, speed and accuracy in solving problems, and be able to convey the solutions offered well so that they are understood by the wider community. At NSC Satria Data 2021, this competition was attended by 312 participants. The highest number of participants from other competitions in Satria Data 2021. The NSC competition system in 2021 is not much different from the previous year. This competition begins with the preliminary round, semifinal round, and finally the final round.
