A researcher has conducted a study analyzing the effects of different types of note-taking among her students. An ANOVA found that there was some difference among three different categories of students: those who took notes by hand, those who took notes on their computer, and those who didnt take notes at all. The researcher then conducts a Bonferroni post-hoc test and found that there were significantly different grades in students who took notes by hand when compared to the others,.
