Method of Generating Statistical Opinion Data

A method of generating statistical data representing respondent selections, comprising:

• providing an interface for provision by a user of a respective data input representing a respondent selection;
• storing data inputs provided by a plurality of respondents representing their respective respondent selections;
• associating a validity time period to each of said data inputs;
• providing an interface for provision by a respondent of an update to a previous data input representing said respondent's selection;
• updating the stored input data to include updates provided by one or more of the plurality of respondents;
• determining a set of valid data inputs according to the respective associated validity time periods;
• aggregating the set of valid data inputs for deriving a respective value of at least one index;
• and
• repeating said determining and aggregating steps to derive a succession of corresponding values of the at least one index.

A method of creating a system for generating statistical data representing user selections, comprising:

• providing an interface for provision by a user of a data input representing said user's selections and assigning a corresponding validity period thereto;
• providing an interface for provision by a user of an updated data input representing updated user's selections and assigning a corresponding validity period thereto;
• providing a memory for storing data inputs provided by a plurality of users representing their respective user selections;
• providing a memory for storing updated data inputs provided by one or more of the plurality of users;
• providing a processor for determining respective subsets of the stored data according to successive associated real-time points the assigned validity periods;
• and,
• providing software for said processor to repetitively compute collective opinion values derived from said successive subsets.
