APPENDIX D CORRECT ANSWERS FOR MENTIMETER TESTS The advantages of a carefully standardized test over an ordinary examination which any one might prepare for his own use are chiefly the characteristics implied in the word “standard.” A standard test is one which has been carefully prepared after extensive experience with similar tests; one which is made exact and objective by the most minute specifications as to how it shall be applied, marked, scored, and interpreted; and one on which many persons of varying degrees of proved ability have been tested and reported, for comparison with the results to be obtained later from testing other persons of undetermined degrees of ability. The purpose of this section of the appendix is to make definite and unmistakable the answers to the questions asked in the Mentimeter tests, in order that each reader may mark and interpret the results of these tests in exactly the same way, that is, in the “standard” way. As was stated in the body of the discussion, each package of test booklets sold is accompanied by a “stencil” which fits over the pages of the printed test in such a manner as to bring the correct answer directly alongside the answer checked or written by the candidate examined, with the result that there is small opportunity for errors in the judgment of the persons marking the answers. If the word checked or written corresponds with the word or words printed on the stencil at that point, the question has been answered correctly, while if the word checked or written by the candidate is less applicable than the one appearing on the stencil, the response is to be marked incorrect. With the aid of the stencils the Mentimeter tests may be marked correctly by inexpensive clerical assistants in from one third to one tenth of the time that would be required for the same work by the most intelligent men working without the stencils. No attempt has been made to print here an exhaustive list of correct answers to each question. The answers printed as correct are merely typical in most cases of the quality of replies that should be accepted. Anything as appropriate as or more appropriate than the printed answer may be given full credit, while anything less satisfactory is to be given no credit at all. To print here all of the correct answers to each question would take more pages than can be allowed for this section of the Appendix and would in many cases cause more confusion than clearness of thought. It is suggested that any question of right or wrong answers which is difficult to decide should be settled arbitrarily by the reader and that a note be kept of just how the matter was decided, in order that any later investigator may have the benefit of his judgment. In some of the tests new solutions will continually be appearing, even after it seems certain that all of the correct answers have been found and catalogued.
