To Determine Whether or Not an IQ Test Is Biased

To determine whether or not an IQ test is biased against some minority group, we need to determine

A) whether the range and standard deviation of the test are the same for minority group members as for other people.
B) whether the authors of the test consulted minority group members during the composition of the test.
C) whether the average score is lower for minority group members than for other people.
D) whether the minority group members do better in school than the test scores predict.
