Professor Gustafson is developing a new intelligence test and wants to ensure the test has good inter-rater reliability. Which of the following strategies will most directly help him achieve this goal?
A. Allowing only a small subset of highly trained researchers to grade the test, because this ensures standardization of test conditions
B. Allowing only a small subset of highly trained researchers to grade the test, because this ensures validity, which is crucial to establish reliability
C. 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
D. Ensuring that a representative sample of participants take the test, as this is the best way to establish reliability

Professor Gustafson is developing a new intelligence test and wants to ensure the test has good inter-rater reliability. The following strategies will most directly help him achieve this goal- (C) By 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

Explanation:

In order to test the inter-rater reliability  of the new intelligence test professor Gustafson should:

From the given option (a) allowing only a small subset of highly trained researchers to grade the test, because this ensures standardization of test conditions is not a valid option because the test is still in the developing stage so, the standardization of the test condition will not serve the purpose

the answer is true!                                          

a factory opens that mass-produces light bulbs.

not sure if that's an answer to your questions but this is an example! : )
