Law: statement or mathematical expression of something that always happens; testable (describes). Theory: broad generalization that is based on observation, experimentation, and reasoning; not testable; is modified as new information is discovered (explains). 4. Introduction. (slide 1 of 3). A key . aspect of solving real business problems is dealing appropriately with uncertainty.. This involves recognizing explicitly that uncertainty exists and using quantitative methods to model uncertainty.. Writing a Hypothesis. Quick Questions.
