Intelligence quotient tests

The Intelligence Quotient Tests for preschool children, school children and adults such as Stanford-Binet, Wechsler group tests, etc. 

We form a quotient when dividing one thing by another. We meet the word frequently when discussing a person s IQ, their intelligence quotient, which we define as (a person s score in an intelligence test 4- the average score) x 100.

Patients are divided into two groups on the basis of current thyroid status euthyroid (TSH < 5 mlU/L) or hypothyroid (TSH > 5 mlU/L). Total serum thyroxine (T4) was also measured. An Intelligence Quotient was derived for each patient using the Hiskey Nebraska Test of Learning Ability and the Griffiths Mental Developmental Scales. The details of the endocrine, psychological and neurophysiological studies are the subject of separate communications. 

Capacity measurements by discharge are most reliable and one would anticipate repeatable readings, but this is not always the case, especially with lead-acid batteries. Independent lab tests, including those at Cadex, have revealed differences in capacity readings of more than 10% under identical test conditions. The reason for this discrepancy is not fully understood other than to realize that batteries are electrochemical devices that exhibit human-like qualities. (Our IQ [intelligence quotient] level also diverges depending on time of day and other conditions.) These tolerances...
