Abstract: An electronic method for generating group data indicative of the collective response of at least a subset of respondents to at least one portion of a time-varying stimulus the method comprising: receiving responses to the time-varying stimulus from respective ones of a plurality of respondent devices, each response including data indicative of a response of a respondent associated with the respective respondent device to the time-varying stimulus; filtering the responses to generate a filtered response data set that excludes responses outside of a timing tolerance relative to a portion of the time-varying stimulus to which the group data is intended to relate; and processing at least a subset of the filtered response data set to generate the group data.
