Document Summary
Psyc2300 - science and scientific methods chapter 5 classnotes. Science: the pursuit of systematized knowledge through observation. A hypothesis must be amenable to systematic testing that could show it to be false. What is observed must be replicable it must occur under prescribed circumstances not once, but repeatedly. Theory: a set of propositions meant to explain a class of phenomena. Primary goal of science is to advance theories to account for data, often by proposing cause effect relationships. Hypothesis: expectations about what should occur if a theory is true. The generation of a theory is perhaps the most challenging part of the scientific enterprise. Consider data that have been previously collected and then decide that a given way of thinking about the data is the most economical and useful. Operationism each concept take as its meaning a single observable and measurable operation. Each theoretical concept would be nothing more than one particular measurable event.
