If I understand the question correctly... the use of a first person's narration in a Gothic-esque story can be used to delve into the characters mind, not only giving the reader a more understandable connection to the character, but it is able to bring taboo and otherwise unsaid dark thoughts into play of the scene
Hi there!
So, based on what the questions asking. It seems that a Flowchart would be most effective because you can see the difference of how close the students test scores are almost identical to them taking notes. You are able to see the decrease or increase of how much attention they give to it and how much they don't.
Hope this helps and have a fantastic day!
