Professor Brown is developing a new intelligence test and wants to ensure the test has good inter-rater reliability. Which of these strategies will most directly help him achieve this goal? D)...

D) Allowing only a small subset of highly trained researchers to grade the test, because this ensures standardization of test conditions

F) Allowing only trained researchers to grade the test, as they will have a good understanding of the proper way to score certain things and will be more likely to agree

A) Ensuring that a representative sample of participants take the test, as this is the best way to establish reliability

B) Comparing scores from the test to scores from a similar test designed to measure the same construct, because this will establish reliability between the tests
