Final answer:
The extent to which a test is unbiased and nondiscriminatory refers to its fairness, which is an integral component of the test's validity.
Step-by-step explanation:
The extent to which a test is unbiased and nondiscriminatory refers to its fairness. Fairness in standardized testing is one aspect of validity, which concerns the accuracy of what the test is supposed to measure. While reliability refers to the consistency of a measure, validity is about both the consistency and the accuracy of what is being measured. Validity ensures that a test actually measures what it purports to measure, and does so in a way that is applicable to all test-takers, regardless of different backgrounds or characteristics. Therefore, when we talk about a test being unbiased and nondiscriminatory, we are referring to its fairness, which is an important part of its overall validity.
