Quizplus · Accepted Answer

A test's reliability is generally increased by conditions that ensure consistent and clear measurement across administrations, such as a distraction-free environment (A), clear instructions (B), and a sufficient number of items to cover the construct adequately (D). However, little variability among individuals on the factor being tested (C) does not increase reliability; it may actually make it harder to distinguish among individuals' true scores, potentially reducing the test's effectiveness in measuring differences.
