Detailed explanation-1: -A valid intelligence test should be able to accurately measure the construct of intelligence rather than other characteristics, such as memory or education level. Essentially, construct validity looks at whether a test covers the full range of behaviors that make up the construct being measured.
Detailed explanation-2: -It is important that intelligence tests be standardized on a regular basis, because the overall level of intelligence in a population may change over time. The Flynn effect refers to the observation that scores on intelligence tests worldwide have increased substantially over the past decades (Flynn, 1999).
Detailed explanation-3: -1 A test is considered reliable if we get the same result repeatedly. For example, if a test is designed to measure a trait (such as introversion), then each time the test is administered to a subject, the results should be approximately the same.
Detailed explanation-4: -Wechsler Scales. A number of scales are based on the IQ. The Wechsler Adult lntelligence Scale (WAIS) is the most widely used intelligence test for adults (Watkins, Campbell, Nieberding, & Hallmark, 1995).
