When two forms of the same test are administered on the same sample immediately one after the other, this procedure will allow the researcher to study:

Correct option is B

When two parallel forms of a test are administered immediately one after another, this assesses alternate-form reliability, which evaluates the consistency of measurement across different sets of items designed to measure the same construct. Since there is no time delay, this specifically examines whether the two forms are equivalent in terms of content sampling, not temporal stability. This is also called equivalence reliability.

Information Booster:
1. Alternate-Form Reliability: Measures consistency across different versions of the same test, assessing content sampling adequacy
2. Immediate Administration: Eliminates time-related factors (learning, maturation, memory) from affecting the reliability estimate
3. Content Sampling: Tests whether different samples of items from the same content domain yield similar scores
4. Practical Applications: Important for situations requiring multiple test versions (security concerns, repeated assessment)
5. Ideal Characteristics: Parallel forms should have equal means, standard deviations, and correlations with external criteria

Additional Knowledge:
• Reliability across time (A): Would require test-retest with a time interval between administrations
• Construct validity (C): Requires examining relationships with theoretically related/unrelated constructs
• Concurrent validity (D): Requires correlating test scores with a criterion measured at the same time
