Final answer:
Content validity is best addressed by ensuring the test covers a representative sample of the subject matter, crucial for comprehensive and aligned assessments.
Step-by-step explanation:
When concerned about the content validity of a classroom test, the most appropriate question to deal with is a) Does the test cover a representative sample of the content? Content validity refers to how well a test measures the entire range of material it is supposed to assess. Focusing on whether the test items reflect a broad and representative sample of the subject matter ensures that the assessment is comprehensive and aligned with the learning objectives.
Option b) pertains to cultural bias, c) to reliability and consistency of scores, and d) to the predictive validity of the test, but none of these directly address content validity. When designing or evaluating a test, it's essential to ensure that the items accurately represent the knowledge or skills being tested, so that the test is not too narrow or skewed towards a particular subset of the content.
Regarding the provided reference material, understanding test validity and reliability is essential for interpreting the outcomes of statistical tests, such as comparing mean exam scores between online and face-to-face classes using the appropriate distribution and determining if the test is of two means or proportions, knowing the population standard deviations, and defining the random variable.
