PSYA01H3 Chapter Notes - Chapter 2: External Validity, Statistical Inference, Case Method
Document Summary
2. 1 empiricism: how to know stuff: dogmatism to describe the tendency for people to cling to their assumptions and the word empiricism to describe the belief that accurate knowledge can be acquired through observation. Keep it simple, stupid : start with the simplest theory possible and then make the theory complicated only if we must, hypothesis: falsifiable prediction made by a theory, your observation should be consistent. 2. 3 the art of looking: empirical method: a set of rules and techniques for observation. 2. 5 observation: discovering what people do: to observe means to use one"s senses to learn about the properties of an event or an object. Validity, reliability, and power- good measures have these characteristics: validity refers to the extent to which a measurement and a property are conceptually related. I. e. completing questionnaires when they are alone: some may not reveal the reason behind the experiment until the end . Blinding the participant: they may use misleading stories or explanations.
