During the second semester of SY 2019 – 2020, students in Mathematics in the Modern World were asked to rate their extent of preparation and level of difficulty. Five classes were considered for this study. Suppose 15 students from each class were randomly selected, (1) is there a significant relationship between their prelim and midterm scores? (2) is there a significant relationship between their extent of preparation and prelim scores? (3) is there a significant relationship between their extent of preparation and midterm scores?
