Document Summary

Field research: research done in natural, real-life settings outside the laboratory. Correlational research: the study of the naturally occurring relationships among variables. When correlational research is extended over time, it is called longitudinal research. Experimental research: studies that seek clues to cause-effect relationships by manipulating one or more factors (independent variables) while controlling others (holding them constant) Dependent variables: the variables being measured, so called because it may. Independent variables: experimental factors that a researcher manipulates depend on manipulations of the independent variable. Random assignment: the process of assigning participants to the conditions of an experiment such that all persons have the same change of being in a given condition: random assignment helps us infer cause and effect. Survey researchers obtain a representative group by taking a random sample. Random sample: survey procedure in which every person in the population being studied has an equal change of inclusion.
