1. A method performed by at least one computer processing executing computer program instructions stored on at least one non-transitory computer-readable medium, the method comprising: (A) receiving data representing a first plurality of social currency event data structures, wherein the first plurality of social currency event data structures includes: data representing first values of the first plurality of social currency event data structures to a first plurality of users; data representing second values of the first plurality of social currency event data structures to a second plurality of users; and data representing a first plurality of existing values of at least one first field shared by the first plurality of social currency event data structures, wherein the receiving comprises: (A) (1) receiving, over a network from a first plurality of computing devices, the data representing the first values of the first plurality of social currency event data structures to the first plurality of users; and (A) (2) receiving, over the network from a second plurality of computing devices, the data representing second values of the first plurality of social currency event data structures to a second plurality of users; (B) identifying a first subset of the first plurality of social currency event data structures based on the first plurality of existing values of the at least one first field shared by the plurality of social currency event data structures; (C) calculating a first value of a statistic based on the first subset of the first plurality of social currency event data structures; (D) identifying a first plurality of existing values of a second field shared by the first plurality of social currency event data structures; (E) calculating a first plurality of normalized values of the second field based on the first value of the statistic and the first plurality of existing values of the second field; and (F) providing, over the network, at least one of the first plurality of normalized values of the second field to a third computing device.
