Systematic reviews
Summary review about the impact of an intervention in which the analyst tries to account for differences in research design and participant characteristics, often using statistical techniques such as meta-analysis.
Theory
A logically interrelated set of propositions about reality.
Deductive research
The type of research in which a specific expectation is deduced from a general premise and is then tested.
Hypothesis
A tentative statement about empirical reality, involving a relationship between two or more variables. Ex.: The higher the poverty rate in a community, the higher the percentage of community residents who are homeless.
Variables
Characteristic or property that can take on different values or attributes. Ex.: Poverty rate, percentage of homeless community residents
Independent variable
A variable that is hypothesized to cause, or lead to, variation in another variable. Ex.: poverty rate
Dependent variable
A variable that is hypothesized to vary depending on or under the influence of another variable. Ex.: percentage of community residents who are homeless
Direction of association
A pattern in a relationship between two variables; the values of one variable tend to change consistently in relation to change in the value of the second variable.
Empirical generalization
A statement that describes patterns found in data.
Inductive research
The type of research in which general conclusions are drawn from specific data.
Serendipitous findings
Unexpected patterns in data that stimulate new ideas or theoretical approaches.
Measurement validity
Exists when a measure measures what we think it measures.
Sample generalizability
Exists when a conclusion based on a sample, or subset, of a larger population holds true for that population.
Cross-population generalizability
Exists when findings about one group or population or setting hold true for other groups or populations or settings.
Causal validity
Exists when a conclusion that A leads to or results in B is correct.
Authenticity
When the understanding of a social process or social setting is one that reflects fairly the various perspectives of participants in that setting.
