Researcher B measured academic preparedness as discrete data because class rank is a ranking system that categorizes students into discrete categories based on their performance (such as top 10%, top 25%, etc.), rather than measuring their performance as a continuous variable. Researcher A measured academic preparedness as continuous data because the percent correct responses on an entrance exam is measured on a continuous scale from 0% to 100%.
