Document Summary
Crim 320 - lecture 2 - review of methods & statistics. Aim of science - to prove/disprove theories. Hypothesis - testable statement about nature of social reality. Measurement - assigning unit of analysis to attribute on a variable. Unit of analysis - person/thing from which data collected. Variable - set of logical attributes that are of interest to researcher. Moving from abstract (concepts) to concrete (measurement of concepts) Conceptualization - process of formulating & clarifying concepts. Dsm-iv - repeated use of substance to extent that it interferes w/ adequate social, vocational, self-care functioning. But cannot say whether def is correct/not. Also - relies on shared understanding of definitional terms. Measurement assumes the possibility of assigning diff values/categories to units of analysis. We measure concepts that vary, which we refer to as variables. Many social science concepts not directly observable. We cannot see education/prejudice in concrete sense. But we can see how much formal schooling they have.
