How well the results of a study apply to individuals and realistic behaviors outside the study |
|
Internal validity |
How well the study provides causal information about behavior |
|
Reliability |
How well results can be replicated |
|
Operational Definition |
The definition of an abstract concept used by a researcher manipulates the concept in the research study Example: smiles mean happiness |
