Indiana University Studies 



No. 27 BLOOMINGTON, INDIANA March 1, 1915 



Introduction 



The investigation which is here reported is the outcome of two 

 requests which reached the psychological laboratory of Indiana 

 University at about the same time, in the autumn of 1913. One 

 came from Mr. S. A. Courtis, requesting that the laboratory under- 

 take to be a clearing-house for the Courtis Standard Tests in 

 Indiana. The other came from a committee of the Indiana City 

 Superintendents' Research Club for cooperation in educational re- 

 search. As a result, twenty of the cities represented in the research 

 club gave the Courtis tests in arithmetic in May, 1914, and sent 

 to the laboratory the tabulated results. These results were worked 

 up in comparative studies and more than seventy charts were pre- 

 pared and used in presenting the data to the meeting of the club 

 at Wabash, Indiana, on October 28, 1914. These charts, which 

 presented the essential facts in a detailed way, were then routed 

 by the secretary of the club and sent to each of the cities which 

 had participated in the investigation. Each city was permitted to 

 use the charts three days. By request, the club voted permission 

 to the University to publish the results in bulletin form. 



Credit for this bulletin is due to the several hundred teachers 

 Avho gave the tests and computed the individual and class scores, 

 to the administrative officers who supervised the giving of the 

 tests and arranged the class and school records for the University, 

 and to the superintendents who have courageously undertaken to 

 measure by scientific methods the results of their work. 



A number of persons have assisted in arranging the data in 

 comparative tables and in making the necessary mathematical com- 

 putations. Mr. Paul Mort corrected most of the class and school 

 record sheets, and computed many of the city and individual 

 medians and variabilities. He also rendered great assistance with 

 the graphs, making the original charts which were sent to the 

 several cities. Miss Glenora Swadener assisted in making the dis- 

 tribution tables and the tabulations under the questionnaire. As-
