Introduction to Sociology, 5/e © 2012 BVT Publishing

Observational Research Naturalistic: advantages & disadvantages Participant

Case Studies Advantages: much info.; new hypotheses Disadvantage: can’t always generalize results to other people

Ethnographic Research Study and entire culture or subculture Close observation of sociological phenomena Understand cultures from an insider’s perspective; then translate that understanding to outsiders Interpret social world by rational analyses

Survey Research Questionnaires: adv. Fast & cheap Disadvantages: bias; wording Interviews: can explain questions; still must guard against bias

Correlational Research Correlation: Not a cause Study how two variables are related Positive correlation=direct relationship Negative correlation=inverse relationship +1=perfect positive correlation -1=perfect negative correlation 0=no relationship

Experimental Research Experimental group: gets exposed to an independent variable Control group: no independent variable; used for comparison Dependent variable: measured Advantage: most control Dis.: artificial

Reliability/Validity Reliability: repeated observations yield similar results Validity: extent to which observations actually yield measures of what they are supposed to measure
