Random error refers to the variability in scores that is not attributed to the construct being measured, but rather to extraneous factors in the testing situation, such as the individual's mood or distractions in the environment. This means that all measurements contain some level of random error due to factors beyond the control of the test itself. Maturation refers to changes that occur naturally over time, such as changes in development or life experiences, and is not necessarily related to the test itself. Regression effect refers to the tendency for extreme scores to move closer to the mean on subsequent tests, which may occur in some situations but is not a universal effect of all tests. Mortality refers to the loss of participants in a study or test, which can impact the sample size and generalizability of the results, but is not a feature of the test itself.
