Hypothesis: A positive correlation will exist between the high schoolers’ likelihood of selecting ethically labeled food and their performance on a subsequent quiz on food sustainability practices.

I ranked the participants based on their frequency of choosing the ethically labeled image. There are 5 pairs of images and the participants that choose correctly will be assigned closer to rank 1; I’m doing this to try to emulate a Likert scale. Similarly, I’m assigning ranks based on the number of correct answers – where participants with higher scores receive higher ranks. I will keep five ranks here for consistency, but they’re split into a range of points. For example, if a participant gets 3 questions right, they will be assigned rank 5. I’m still currently assigned the ranks (because I don’t know how to do it quickly, unfortunately). Then, I will calculate Spearman’s rank correlation coefficient to determine if there’s a significant correlation between the two.
