The research measures what it sets out to measure.
1 of 14
Control Group
You can compare participants you haven't manipulated with participants you have.
2 of 14
Qualitative Data
If this is collected more insight can gained into why we behave in the way we found in the research.
3 of 14
Demand Characteristics
These lower validity because the researcher is not measuring the truth. Prevent by using a single blind.
4 of 14
Individual Differences
Reduces validity because you can't be sure that the difference between two conditions is down to the IV. Can be overcome if participants are randomly allocated to groups.
5 of 14
Order Effects
Practice, boredom, fatigue. Can be overcome by using counterbalancing.
6 of 14
External
The results are generalisable to other people, places etc that haven't been used in the research.
7 of 14
Temporal
The time/era in which the research takes place should not affect the results. Would the results still hold true in 50 years time?
8 of 14
Population Validity
The sample needs to be representative of the target population. There should be no age, gender or race bias unless it is relevant to the target population.
9 of 14
Ecological
The setting for the research should reflect where this behaviour would naturally occur. The task should be a task that people naturally undertake in daily life. I.e. it should have mundane realism.
10 of 14
Face / Content
Examining the content of the test to see if it looks like it measures what it is supposed to measure.
11 of 14
Construct
Whether the test or method can be used to support the underlying theoretical construct.
12 of 14
Concurrent
Involves comparing a new method or test with an already well established one that claims to measure the same variables.
13 of 14
Predicitive
Whether the test will predict future performance indicated by its results.
