Answer :
It is difficult to determine Jacob's exact IQ based solely on the information provided. However, it is likely that his IQ would be considered above average for his age group. 50 is Average IQ
However, without administering a standardized IQ test, it is impossible to provide an accurate estimate of his IQ score. Jacob is 9 years old and academically performs at a 12-year-old level. While it indicates that he may have a higher than average IQ, it's not possible to provide an exact IQ score without proper testing. IQ tests take into information various factors and are specifically designed to measure intelligence.
The total score obtained from a series of standardised tests or subtests designed to gauge human intelligence is referred to as the intelligence quotient (IQ). The name "IQ" was coined by psychologist William Stern to represent the scoring scheme he advocated in a 1912 book for intelligence tests at the University of Breslau. Stern used the term Intelligenzquotient, which is a German term, to refer to the system. In the past, the mental age scores a person received after taking an intelligence test was divided by their chronological age, which was expressed in years and months. The resulting fraction (quotient), multiplied by 100, produced the IQ score. A normal distribution is created from the raw score, having a mean of 100 and a standard deviation of 15 .
