Question

Researcher A conducts a study in which she surveys 50 college students and finds that students who report eating a high-protein breakfast have a substantially higher GPA than students who report that they eat a low-protein breakfast. She finds that this difference was statistically significant. A blogger hears about this finding and writes a blog saying that all students would get better grades if they started eating a high-protein breakfast. Which of the following statements are potential problems with this conclusion about what students should do?[Select all that are correct.]
a. The result was based on self reports, and it's possible that the students' reports are not accurate
b. Although the effect might be true on average, it might not be true of all people
c. The blog is drawing a conclusion about causation based on a mere correlation
