What aspect of standardized tests helps to minimize bias?

• A. Item selection process
• B. Random sampling
• C. Subjective scoring methods
• D. Expert reviews

Answer: (B)

Random sampling is crucial in standardized tests as it ensures that the sample of test-takers reflects the broader population from which they are drawn. By randomly selecting participants, researchers can achieve a diverse representation of different demographics, backgrounds, and abilities. This diversity can help to mitigate biases that may arise if certain groups are overrepresented or underrepresented. A well-represented sample contributes to the generalizability of the test results and helps ensure that the test measures what it is intended to measure across all groups, rather than favoring one group over another.

In contrast, other aspects like item selection, subjective scoring methods, and expert reviews may not inherently minimize bias in the same way. For example, the item selection process could unintentionally favor certain cultural references or knowledge bases, which may disadvantage certain test-takers. Subjective scoring methods can introduce personal biases from scorers, and while expert reviews can be beneficial, they may not be comprehensive enough to identify every bias present in the test materials.
