Document Summary
A research design is a broad structure that guides the collection/analysis of data. It helps you decide what it is that you want to accomplish. Reliability: concern regarding whether the measures of social science concepts are reliable. The same results should be achieved is the same measurement technique was administered several times. Replicability: if others are able to repeat it and get the same results. Validity: there are three main types: measurement or construct validity: refers to whether an indicator actually does measure what it is supposed to measure, internal validity: relates to causality. It is common to refer to proposed causes as independent variables and the corresponding effect as the dependent variable. Dependent variable: external validity: involves two things. Whether a study"s findings are applicable in settings outside the research environment. In addition to this it is important to determine if the results can be generalized.
