### MEASUREMENT OF INTELLIGENCE

 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Bethany has a mental age of 5. This means that she must:
 A Be 5 B have answered test items that could be answered by an average 5-year-old C have answered at least half of the items considered appropriate for the average 6-year-old D ave an intelligence level that matches her have answered test items that could be answered by an haverage 5-year-old
Explanation:

Detailed explanation-1: -Bethany must b. have answered intelligence test items that could be answered by an average 5-year-old. The question doesn’t give an chronological age for Bethany. So, the answer must be b. Bethany could be a 3 year old and have an above average intelligence.

Detailed explanation-2: -a numerical scale unit derived by dividing an individual’s results in an intelligence test by the average score for other people of the same age. Thus, a 4-year-old child who scored 150 on an IQ test would have a mental age of 6 (the age-appropriate average score is 100; therefore, MA = (150/100) × 4 = 6).

Detailed explanation-3: -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.

Detailed explanation-4: -Hence, the required mental age for a group of 12-year children is 9.6 years or more and 16.8 years or less. where MA is mental age and CA is chronological age.

Detailed explanation-5: -The reason for this test was to score the individual and compare it to others of the same age group rather than to score by chronological age and mental age. The fixed average is 100 and the normal range is between 85 and 115. This is a standard currently used and is used in the Stanford-Binet test as well.
