BIOL 2000H Lecture Notes - Lecture 2: Scientific Method, Stoichiometry, Statistical Hypothesis Testing
Document Summary
Stoichiometry: mass must be conserved: matter and energy cannot be created or destroyed. Make sure your evidence is solid and correct. Other scientists will criticize your work heavily if it is published in a journal: more so if it is a well known journal. Descriptive questions are not always necessary for the scientific method: descriptive questions have one distinct answer. Causal questions are always necessary for the scientific method: causal questions have infinite answers, serve as the basis for your hypothesis. Hypothesis: an explanation for a puzzling observation: answer to the causal question, some hypotheses have more merit than others, scientific inquiry seeks to verify or refute hypotheses, can be false, hypotheses should; Not violate and known properties of the world. Hypotheses can complement each other in different areas of science. Different fields can have proximate and/or ultimate hypotheses. Causal question (cid:862)why is it like that? (cid:863: 3.
