Document Summary
Empirical investigation methods: an integral feature of scientific practice is the use of careful observation, measurement, and manipulation of variables, a variable is the object, concept or event being measured. Consistency (don"t contradict each other), coherence (speak the same language), and convergence (independently come to the same result) as markers of reality. In order to check for consistency and coherence, we need to be able: consider if you wanted to study if shyness causes loneliness. Laws as universal generalizations: generalizations point to causation and laws, and therefore support deep explanation, science affords intervention in reality, i. e. power to change things, the generalizability-discrimination (contextual sensitivity, individual differences) tradeoff. Increasing the evidence pool, e. g. number of participants, is one way to increase generalizability. Population is the group the researcher wants to generalize about: science almost always relies on samples, the problem is properties and patterns of the sample may not be properties of the population, i. e. will not generalize.
