Abstract:
1. A computer-implemented method for assessing survey presentations, said method comprising: generating, by a computer, a plurality of survey presentations, each survey presentation having a same information content and number of questions, and a different order of said number of questions, wherein offering, by said computer, said plurality of survey presentations to selections of a population grouped into sets of similar profiles to obtain observed responses in said feature space; estimating, by said computer, an unbiased response in said feature space from said observed responses, based upon a least mean square estimation of said observed responses to said plurality of survey presentations; determining, by said computer, a measurement error of the difference between said observed responses in said feature space and said unbiased response in said feature space for each question and for each of said sets of similar profiles; and removing, by said computer, those survey presentations, exceeding a threshold value of said measurement error, based on said difference of said observed responses in said feature space and said unbiased response in said feature space, from said plurality of survey presentations to provide a subset of favorably assessed survey presentations.
