Presently the Gaming Industry of Australia is attempting to define various new 'definitions of Standard Deviation'...in a concept to define infield metrics for the analysis of machines in terms which imply whether a machine is being operated with respect to its defined percentage or in fact outside its defined region - i.e.. Illegally manipulated.
My understanding of the Standard Deviation metric does not fit the mixed (confused) proposals of the industry. Therefore I ask if a suitable mathematician may be available to examine the problem. The gaming industry seems to want the metric used in terms of a periodic infield observable, my feeling is that it is inappropriate and another method must be provided if possible. The first part is to confer the inappropriate aspect of STDDEV to periodic observations. After which appropriate methods are required! Here is the problem: Imagine a game with two components, the base game and a feature. During the base game prizes from say 20 units to 5000 are awarded (the standard deviation being well defined). During the base games at statistically 1 in say 120 occurrence, a feature game occurs which uses the same base game prizes though all are multiplied by 3 i.e. 60 to 15000 unit prizes. What method should be used to define the standard deviation? For anyone able to provide a provable solution a monetary prize of at least $250US is available. Regards, David H.
