Research Ch. 2
Chapter 2 of Research Design
Term | Definition |
---|---|
Variables | Attributes of sampling units, events, or conditions that can take on two or more values, or observed or measured events or conditions that vary or are likely to vary. |
Varied Replication | Repeating (replicating) a previous study but with some new twist. |
Working Hypotheses | An empirically testable supposition, the experimental hypothesis. |
Operational Definitions | The meaning of a variable in terms of the operations (empirical conditions) used to measure it or the experimental method involved in its determination. |
Parsimony | The quality of economy in a statement or proposition, so that it is not overly wordy or unduly complex. |
Replication | Research designed to assess the repeat-ability of a result. |
Serendipity | Making a chance discovery. |
Theoretical Definitions | The meaning of a variable in abstract or conceptual terms. |
Theory | A set of proposed explanatory statements or propositions connected by logical arguments and by explicit and implicit assumptions. |
Variable | An event or a condition the researcher observes or measures or plans to investigate that is likely to vary. |
Coherence | The high degree to which the components of a theory or hypothesis "stick together" logically |
Construct | Abstract expression, term, or concept that is formulated ("constructed") to serve as a casual or descriptive explanation. |
Context of Discovery | Included the initial hunches, questions, or insights and the resulting conjectural statements or suppositions that give direction to researchers' observations. |
Context of Justification | Included the empirical evaluation of conjectural statements or suppositions and the evidence-based defense of conclusions and generalizations. |
Dependent Variable | A variable the changes in which are viewed as dependent on changes in one or more other variables. |
Experimental Hypotheses | |
Falsifiability | Karl Popper's proposition that a conjecture or theoretical assertion is scientific only if it can be stated in such a way that it can, if incorrect, be refuted by some empirical means. |
Hypothesis | A conjectural statement or supposition |
Hypothesis-generating Heuristics | Strategies or circumstances that lead to testable hypotheses. |
Independent Variable | A variable on which the dependent variable depends; in experiments, a variable that the experimenter manipulates to determine the degree to which there are effects on another variable. |
Moderator Variables | Conditions that alter the relationship between independent and dependent variables. |
Occam's Razor | The principle that explanations should be as parsimonious as possible. |
Variables | Attributions of sampling units, events, or conditions that can take on two or more values, or observed or measured events or conditions that vary or are likely to vary. |
Varied Replication | Repeating (replicating) a previous study but with some new twist. |

Dependent Variable | A variable the changes in which are viewed as dependent on changes in one or more other variables. |
Experimental Hypothesis | The experimenter's working hypothesis; also an alternative to the null hypothesis (Ho) in null hypothesis significance testing. |
