Agroup of scientists have developed a test to evaluate differences in intelligence among local populations of urban cities. to avoid certain pitfalls, the test is nonverbal. while beta testing the new process, the developers realize the test has strong reliability but poor validity. what is the best way to solve this problem?

The development team should redesign the test until they find the results correlate well with other measures of intelligence.

Explanation:

The validity of an Intelligence Test is often a subject of debate, and sometimes IQ is the most widespread standard for assessing the level of "intelligence" given the traditional view on intelligence as a measure of very known habilities: mathematical, spatial, verbal, logic and memory.

If a test is to be valid, it should demonstrate a direct link between test scores and traits. It must accurately describe the pure intelligence rather than measuring things often taught as mediated through the educational process.

The IQ test is internationally acknowledged to be the most reliable and valid test, so any tests that have a similar criteria will also be highly contributing to measuring intelligence in ways we often compare to educational level.

Furthermore, intelligence tests also need to update and include an international and cultural background into account for representing a score that yields most valid the actual intelligence.

the answer would be in this answer. someone already asked the question.
