Independent Samples are samples that are not linked experimentally and the measurement of one sample has no effect on the others. Research experiments usually involve some manipulation of independent variables and measurement of dependent variables to investigate the relationship between them. Indirect Approach is one where the true purpose of a research project is disguised. Indirect approaches are used when revealing the true purpose of the research would bias the responses given by participants. Inferential Analysis is the analysis of data to test a specific hypothesis.
Information involves the analysis and interpretation of data to describe something about a market.
Informed Consent is the principle that researchers should try to avoid both uninformed and misinformed participation by subjects in research. Interaction Effect is the effect of all the factors working together, which is greater than the sum of the separate effects. Interactive Testing Effect see pre-test manipulation interactive bias. Interdependence Techniques are types of multivariate analysis techniques that are used where no distinction is made as to which variables are dependent or independent. Interdependency is when variables each influence each other to some degree.
