Abstract
Beginning with data cards which carry thereon a question or a statement to be a subject of a survey, such cards being pre-punched with appropriate indicia signifying the question being asked or the position being tested, the interviewer submits such position or question-carrying card to the interviewee who, upon reading the question or statement to himself, selects one of several possible categories between two extremes, as represented by a slot in a sequentially designated series of slots in a container, inserts such card in the selected slot representing his degree of agreement or disagreement with the question or position statement, such card being automatically received by an envelope marked correspondingly to the designation adjacent the slot, for later sorting and computer compilation of all the cards in each envelope and survey results which are free, to a maximum degree, from interviewer influence of interviewee.
