| Varied Replication | Repeating (replicating) a previous study but with some new twist.
🗑
|

||||
| 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.
🗑

| 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.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
