Detailed explanation-1: -The WPPSI-R is an intelligence test for children aged 3 years, 0 months through 7 years, 3 months. The original version of the WPPSI was developed in 1967 for ages 4 to 6 Vi years, and the WPPSI-R was revised in 1989.
Detailed explanation-2: -Validity is the extent to which a test measures what it claims to measure. 1 It is vital for a test to be valid in order for the results to be accurately applied and interpreted.
Detailed explanation-3: -Spearman is well-known for proposing the g factor, which refers to general mental ability. He observed that children’s school performance was essentially consistent across all school subjects, rather than being high in some subjects and low in others.
Detailed explanation-4: -IQ was originally computed by taking the ratio of mental age to chronological (physical) age and multiplying by 100. Thus, if a 10-year-old child had a mental age of 12 (that is, performed on the test at the level of an average 12-year-old), the child was assigned an IQ of 12/10 × 100, or 120.
