180 seniors taking Pre Calculus are randomly divided into classes. The school is testing both teaching style as well as the use of technology on student performance in math. They have 2 teaching styles: traditional and progressive. They also are testing the use of laptops, graphing calculators, and no technology. After the experiment was conducted they found that students in a traditional class with a graphing calculator scored significantly better than the other groups. Explain what "significantly" means in the statistical context for this study.
