Question1
Face validity
Face validity is a type of validity in non-psychometric or non-statistical terms. It does
not refer to what the test measures, but rather to what it appears to measure. It has
to do with whether the measure 'looks valid' to test-takers who have to undergo
testing for a specific purpose. In this sense, face validity is a desirable characteristic
for a measure.
Content validity
is the estimate of how much a measure represents every single element of
a construct (i.e. does the content of the test fully cover the important areas of the domain
being assessed)
It is a non-statistical type of validity and refers to a specific procedure in constructing a
psychological measure
A frequently used procedure to ensure high content validity is the use of a panel of subject
experts to evaluate the items during the test construction phase
Content validity is especially relevant for evaluating achievement, educational, and
occupational measures.
Content validity is usually not the most appropriate aspect of validity to establish for
aptitude and personality measures (the validation of aptitude and personality measures
usually requires validation through criterion-prediction procedures).
Face validity: it does not refer to what the test measures, but rather to what it appears to measure.
Face validity requires a personal judgment, such as asking participants whether they thought that
a test was well constructed and useful.
Face validity – does not refer to what the test measures, but to what it appears to measure.
Content validity – involves determining whether the content of the measure covers a
representative sample of the behaviour domain / aspect to be measured.

Biographical context referring to the physical bodily structure and functions,
