Ensemble averaging represents the average of ____________(a) unsteady

1.	Ensemble averaging represents the average of ____________(a) unsteady quantities(b) steady quantities(c) identical quantities(d) mean quantitiesThe question was posed to me at a job interview.I would like to ask this question from Turbulence Modelling topic in section Turbulence Modelling of Computational Fluid Dynamics
Answer» The correct CHOICE is (c) identical quantities Easiest explanation: This is useful for identical quantities. Identical in the sense, that they have similar properties in some concern. A NUMBER of quantities which have the simultaneous VARIATIONS can be AVERAGED using this method.
