answers: Construct validity
context: with (convergent validity), not associated with things it should not be associated with (discriminant validity). Construct validity evidence involves the empirical and theoretical support for the interpretation of the construct. Such lines of evidence include statistical analyses of the internal structure of the test including the relationships between responses to different test items. They also include relationships between the test and measures of other constructs. As currently understood, construct validity is not distinct from the support for the substantive theory of the construct that the test is designed to measure. As such, experiments designed to reveal aspects of the causal </s> alternate spelling "-metre" is never used when referring to a measuring device. Measuring instrument A measuring instrument is a device for measuring a physical quantity. In the physical sciences, quality assurance, and engineering, measurement is the activity of obtaining and comparing physical quantities of real-world objects and events. Established standard objects and events are used as units, and the process of measurement gives a number relating the item under study and the referenced unit of measurement. Measuring instruments, and formal test methods which define the instrument's use, are the means by which these relations of numbers are obtained. All measuring </s> most commonly used by scholars and the general public. Jonathan Dolhenty states there seem to be only three functional, effective tests of truth. He lists these as the correspondence, coherence and pragmatic theories of truth. The opinions of those with significant experience, highly trained or possessing an advanced degree are often considered a form of proof. Their knowledge and familiarity within a given field or area of knowledge command respect and allow their statements to be criteria of truth. A person may not simply declare themselves an authority, but rather must be properly qualified. Despite the wide respect given to
