Turning hunches into testable hypotheses, validated by experiment and analysis, to guide decisions.
Hypothesis testing transforms "I think this is true" into "the evidence shows this." It spans defining problems, constructing testable hypotheses, designing experiments, collecting and analyzing data, and applying findings to decisions. It is the core of evidence-based reasoning.
Measures proportional reasoning, probabilistic reasoning, correlational thinking, and hypothetico-deductive reasoning across Concrete, Transitional, and Formal levels, providing domain-specific evidence for hypothesis testing level boundaries.
5-tier belt system requiring hypothesis testing as a core competency from Green Belt onward, providing specific statistical tool criteria for checklist design.
Authoritative guide to hypothesis testing, p-values, confidence intervals, and Bayesian thinking. Provides academic authority for the statistical reasoning field.
U.S. government-accredited statistical handbook defining standard procedures for hypothesis testing, experimental design, and reliability analysis. Provides direct evidence for statistical methodology criteria in checklists.
