12. A system that automatically performs marketing actions, the system comprising: a service information display located at an outlet configured to receive consumer input regarding a marketable item; communication interface configured to receive from the service information display the consumer input and contextual input associated with the consumer input; a storage segmented into data groups that maintain consumers data and associated contextual data having similar characteristics, each of the segmented data groups includes sufficient consumers data and associated contextual data to enable statistical analysis; a processing module configured to: place the consumer input and associated contextual data into one or more of the segmented groups; and compute for the marketable item a projected marketing effectiveness corresponding to one or more pre-determined changes of respective one or more marketing attributes associated with the marketable item, where the one or more pre-determined changes to the respective one or more marketing attributes define a marketing action specified in a rule associated with one of the one or more segmented groups; and a rule engine configured to automatically change the one or more marketing attributes associated with the marketable item according to the marketing action specified in the rule when the projected effectiveness computed using the one or more pre-determined changes specified in the rule is equal to or exceeds a corresponding pre-defined threshold specified in the rule that is compared to the computed projected effectiveness, and to maintain the one or more marketing attributes unchanged when the projected effectiveness computed using the one or more pre-determined changes specified in the rule is less than the corresponding pre-defined threshold specified in the rule that is compared to the computed projected effectiveness, wherein the marketing action corresponding to the one or more pre-determined changes to the respective one or more marketing attributes associated with the marketable item include one or more of: a change to inventory level associated with the marketable item, or a change to an amount of advertising presented in relation to the marketable item; wherein the processing module is further configured to: determine for a particular segmented group from the one or more segmented data groups an average metric value, M, and a standard deviation value, S, for metric values associated with each of one or more data records in the particular segmented group, determine a new average metric, M′, according to M′=M+0.5S, determine a new standard deviation value, S′, based on the new average metric M′ and the metric values associated with each of the one or more data records in the particular segmented group, and segment the particular segmented group into at least two new segmented groups based, at least in part, on a determination that number of data records in the particular segmented group whose metric value is within S′ from the new average metric M′ exceeds a pre-determined group size threshold.
12. A system that automatically performs marketing actions, the system comprising: a service information display located at an outlet configured to receive consumer input regarding a marketable item; communication interface configured to receive from the service information display the consumer input and contextual input associated with the consumer input; a storage segmented into data groups that maintain consumers data and associated contextual data having similar characteristics, each of the segmented data groups includes sufficient consumers data and associated contextual data to enable statistical analysis; a processing module configured to: place the consumer input and associated contextual data into one or more of the segmented groups; and compute for the marketable item a projected marketing effectiveness corresponding to one or more pre-determined changes of respective one or more marketing attributes associated with the marketable item, where the one or more pre-determined changes to the respective one or more marketing attributes define a marketing action specified in a rule associated with one of the one or more segmented groups; and a rule engine configured to automatically change the one or more marketing attributes associated with the marketable item according to the marketing action specified in the rule when the projected effectiveness computed using the one or more pre-determined changes specified in the rule is equal to or exceeds a corresponding pre-defined threshold specified in the rule that is compared to the computed projected effectiveness, and to maintain the one or more marketing attributes unchanged when the projected effectiveness computed using the one or more pre-determined changes specified in the rule is less than the corresponding pre-defined threshold specified in the rule that is compared to the computed projected effectiveness, wherein the marketing action corresponding to the one or more pre-determined changes to the respective one or more marketing attributes associated with the marketable item include one or more of: a change to inventory level associated with the marketable item, or a change to an amount of advertising presented in relation to the marketable item; wherein the processing module is further configured to: determine for a particular segmented group from the one or more segmented data groups an average metric value, M, and a standard deviation value, S, for metric values associated with each of one or more data records in the particular segmented group, determine a new average metric, M′, according to M′=M+0.5S, determine a new standard deviation value, S′, based on the new average metric M′ and the metric values associated with each of the one or more data records in the particular segmented group, and segment the particular segmented group into at least two new segmented groups based, at least in part, on a determination that number of data records in the particular segmented group whose metric value is within S′ from the new average metric M′ exceeds a pre-determined group size threshold. 22. The system of claim 12 , wherein the service information display includes at least one of: a touch screen, an informational kiosk, and a PDA.
