Final answer:
William's reported improvements in managing test-related anxiety and fear of failure indicate that his therapeutic outcome would likely be deemed a success at the end of his therapy.
Step-by-step explanation:
William's progress at the end of his therapy, where he reported fewer anxiety symptoms and a better ability to manage his fear of failure, will most probably be viewed as a success at termination. In the context of therapy, successful outcomes are usually characterized by a reduction in symptoms and improved coping strategies, which William has achieved. This is analogous to a college student adjusting their study habits and improving their test scores with help from their academic success center.
Likewise, in the scientific method, a rejected hypothesis can still lead to a successful experiment if it provides valuable data and insight.
