Validity is also dependent on the measurement measuring what it was designed to measure, and not something else instead. [6] Validity (similar to reliability) is a relative concept; validity is not an all-or-nothing idea.

The validity of each sentence completion test must be determined independently and this depends on the instructions laid out in the scoring booklet. Compared to positivist instruments, such as Likert-type scales, sentence completion tests tend to have high face validity (i.e., the extent to which measurement items accurately reflect the concept ...
The following presents a non-exhaustive list of sources whose reliability and use on Wikipedia are frequently discussed. This list summarizes prior consensus and consolidates links to the most in-depth and recent discussions from the reliable sources noticeboard and elsewhere on Wikipedia.
For example, widespread citation without comment for facts is evidence of a source's reputation and reliability for similar facts, whereas widespread doubts about reliability weigh against it. If outside citation is the main indicator of reliability, particular care should be taken to adhere to other guidelines and policies, and to not unduly ...
