|
Internal Validity - General |
Where the study really is testing what it says it is. |
|
|
Assessing Internal Validity |
Face validity- the study of measure is scrutinized to see if on the surface its an accurate reflection. |
|
|
Improving internal validity |
Look at the questions that are performing inconsistently and change them then do the split half again |
|
|
External Validity |
The extent to which the findings of research can be generalized across people, places or time |
|
|
Population validity |
The extent to which the research findings can be generalised to the target population and to other people |
|
|
Temporal Validity |
The extent to which the research findings can be generalized to other periods of time |
|
|
Ecological Validity |
The extent to which the research findings can be generalised to other settings. If a study has mundane realism it may have ecological validity, but if the setting of the study is very specific it might not be possible to generalise to other settings |
|
|
Assessing External Validity |
To assess the external validity of a study mundane realism, experimental realism, where it took place, the sample of a study and when it took place should all be considered. |
|
|
Improving External Validity |
Finding the questions not performing correctly and changing them |
|
|
Reliability |
It if it 'Consistent' |
|
|
Reseacher Reliability |
More than one researcher conducting the experiment and gathering evidence the same way. Researcher reliability will come from if the results are the same. |
|
|
Inter rater reliability |
Observation based. Whether two or more observers agree with each other, if so they record exactly the same data |
|
|
Assessing Researcher Reliabiltiy |
comparing the scores of the results to see if they agree, possibly doing a correlation depending on the type of results |
|
|
Improving researcher reliability |
Pilot the study and detailed standardised instructions should be written to ensure consistency. Careful training of researchers |
