RQ: To what extent does a correlation exist between high schoolers’ likelihood of selecting ethically labeled food and their performance on a subsequent test on food sustainability practices?

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.

This is an example of the data points I have to look through for each participant on my survey: 5 / 16

C) By promoting crop resilience to pests and diseases, B) No synthetic pesticides or GMOs, a) Use of synthetic pesticides and fertilizers, A) Animal welfare in farming practices, and B) Applying irrigation methods without considering water conservation.

TRUE USDA Organic At least 95% organically produced ingredients (excluding water and salt)


FALSE B) Alteration of plant defense mechanisms

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.
