- Face validity
Face validity is a property of a test intended to measure something. The test is said to have face validity if it "looks like" it is going to measure what it is supposed to measure. [http://www.chssc.salford.ac.uk/healthSci/resmeth2000/resmeth/validity.htm] For instance, if you prepare a test to measure whether students can perform multiplication, and the people you show it to all agree that it looks like a good test of multiplication ability, you have shown the face validity of your test.
Some people use the term face validity only to refer to the validity of observers who are not expert in testing methodologies. For instance, if you have a test that is designed to measure whether children are good spellers, and you ask their parents whether the test is a good test, you are studying the face validity of the test. If you ask an expert in testing spelling, some people would argue that you are not testing face validity (Anastasi 1988, pg. 144). This distinction seems too careful for most applications. Generally face validity means that the test "looks like" it will work, as opposed to "has been shown to work".
There are many other types of validity [http://www.socialresearchmethods.net/kb/measval.htm Social Research Methods] . Face validity is often contrasted with
Content validity .Simulation
In simulation, the first goal of the simulation modeler is to construct a model that appears reasonable on its face to model users and others who are knowledgeable about the real system being simulated. [1] If these experts feel the model is adequate, then it has face validity.
