how to interpret an ROC curve and its AUC value to evaluate a binary classification model over all possible classification thresholds?

This query falls outside the scope of the Level 7 Diploma in Strategic Management and Leadership. The qualification focuses on strategic direction, governance, and organisational capability, not data science metrics like ROC curves or AUC values. As Programme Editor, I advise directing technical modelling questions to relevant data analytics resources. For this OTHM Level 7, our guidance centres on how the 120-credit structure supports MBA top-up progression, Ofqual regulation, and strategic leadership competencies. We provide decision-grade insights on fees, duration, and unit assessments for working managers. If you require clarification on the diploma’s strategic units, accreditation status, or how it compares to an MBA, please specify. We remain focused on delivering evidence-based guidance for senior professionals navigating postgraduate strategic management qualifications within the UK Regulated Qualifications Framework.
