I have collected questions from 10th grade students about genetic engineering before and after learning about the subject and classified the questions based on their cognitive level..
Before learning about the subject, I collected a total of 45 student questions. I classified 28 of those as "input" (basic) questions, 8 questions as "processing" (intermediate) and 9 as "output" (advanced).
After learning about the subject, I collected from the same students 28 questions, distributed as follows: 11 "input", 7 "processing" and 10 "output".
What test is appropriate to see if the distribution of student questions among the three categories is different? I tried conducting a prop.test but that only distinguishes between two categories (success and failure). Thanks.
