Choosing employees by mental and physical tests . or testing this quality is called a dy-namometer (page 216) as nearly all strength-record-ing devices are designated.

Asmany trials as they desired were given and the highestrecord recorded. The machine is a spring-and-dial 216 CHOOSING EMPLOYEES device, and tests are made by simply squeezing the ap-paratus in the hand. The dials of this dynamometerusually read in kilograms, and the average record forwomen is approximately 25, as we found in forty testscomputed. The record depends on the nationality, soan average must be somewhat arbitrary, Americangirls ranging around 23 kilograms and foreign girls at26. An element of grit and determination enters intothe effort, so that the record is partially one of mentalqualities also; just how much we have not been able todetermine. A ratio between this and muscular meas-urements should give valuable will-power The Dynamometer for Testing Grip Courtesy of the Kny-Scheerer Corporation There are various makes of dynamometers for testing thestrength of grip and records will vary somewhat with the in-strument used. The range of right-hand grip power variesfrom 17 to about 70 kilograms. (A kilogram is about ) The Naval Academy demands a standard of 53 fora man of average height. A class of 249 Columbia students ofaverage height averaged 52 kilograms. This is hardly typical,however, of human average on a first test as most of thesemen had some physical training to develop grip average runs at 50 on the best record out of several trialsin the first test, the subjects being mostly foreigners. For-eign women on jobs which would develop grip made women on miscellaneous jobs made 23. This testis useful for screwing operations or any job requiring a strongclasp.
