Most Frequently Used Digit

All of the digits which we use to make numbers get a lot of use -- in fact I'll bet you use all of them many times a day. -Doctor Patrick, The Math Forum Check out our web site! http://mathforum.org/dr.math/

It stated that if you extract and compare a large number of digits from real life sources (birth dates, company balances, temperatures...), there actually exists an asymmetric distribution. The digit "1" is supposed to be more frequent than the "2", which in turn is more frequent than the "3" and so on. Furthermore, this study described a procedure to use this phenomenon to distinguish between arbitrarily set values (such as a fake income declaration) and values that evolved in real life. Have you heard anything about this theory, or do you know of anyone who has had anything to do with a similar subject who might help me find this study? Thanks in advance! Carsten

Note that this answers a slightly different question than "What is the most commonly used digit?", although the two are closely related. A starting point is the following web page in our archives: Benford's Law http://mathforum.org/library/drmath/view/52762.html -Doctor Douglas, The Math Forum http://mathforum.org/dr.math/
