Question

Quizplus · Accepted Answer

IQ is defined differently by different developers, which can lead to differences in the types of items included on IQ tests. Additionally, even when two tests share the same definition of IQ, the specific items chosen to measure that construct may vary based on the test developers' preferences and goals. A and B are not accurate explanations, as IQ tests aim to measure a general cognitive ability, and while different test takers may perform differently, the items themselves are typically standardized. D may be a possible factor, but it is not the most likely explanation for differences between IQ tests.
