Question

Quizplus · Accepted Answer

A double-blind experiment is most appropriate for this question because it eliminates bias from both the participants (students) and the researchers. In this setup, neither the students nor the researchers know which group is using the Addison Wesley Longman Algebra I text and which is using the current text, ensuring that the observed outcomes are a result of the texts themselves rather than preconceptions or expectations.
