q1 i? The individual Binet scale's time cost restricts its employment to special cases, while a group scale permits examining fifty or a hundred children in an hour, with further labor only in scoring and tabulating. → Bell 1919

q1 · i? · theoretical · r2

The editorial contrasts the Binet scale, whose per-pupil individual examination "restrict[s] its employment to special cases," with a group scale that may examine "fifty or a hundred children" per hour. This is the editor's comparative argument, not a measured trial.

"Schoolmen generally have come to see the advantages of the Binet measurements of intelligence, but the necessity of examining each pupil individually has put such a time cost on the use of the scale as to restrict its employment to special cases. With such a group scale fifty or a hundred children may be examined in an hour, and the only further labor is found in scoring and tabulating the results."
