T scores have a mean of 50 with a standard deviation of 10. This means a score that falls at 50 or within 10 points above or below 50 is considered average, and typical of the population. The farther away from 50 a score falls, the more atypical it is. Each test tends to use their own classifications and ranges. scores have a mean of 50 with a standard deviation of 10.

The name Surrey is derived from Suthrige, meaning southern region, and this may originate in its status as the southern portion of the Middle Saxon territory. If it ever existed, the Middle Saxon kingdom had disappeared by the 7th century, and Surrey became a frontier area disputed between the kingdoms of Kent, Essex, Sussex, Wessex and Mercia, until its permanent absorption by Wessex in 825.
The name COCKERHAM is of English origin, designating one who came from Cockerham (homestead on the Cocker River) in Lancashire, England. The name is variously spelt COCKERHAM, COCKRUM, COCKRAM, COCKRAN and COCHRAN. Some researchers suggest the American founder of the Surry Co, VA family was one William COCKERHAM of Dorset, England. He registered his pedigree with the Hearlds in their Visitation to Dorset in 1623 when he was thirty years of age.
