Stone combined measures of other abilities with this in a total score for amount done correctly in 12 minutes. Stone also scored the correctness of the additions in certain work in multiplication. Courtis uses a sheet of twenty-four tasks or 'examples,' each consisting of the addition of nine three-place numbers as shown below. Eight minutes is allowed. He scores the amount done by the number of examples, and also scores the number of examples done correctly, but does not suggest any combination of these two into a general-efficiency score. 927 379 756 837 924 110 854 965 344 --- The author long ago proposed that pupils be measured also with series like _a_ to _g_ shown below, in which the difficulty increases step by step. _a._ 3 2 2 3 2 2 1 2 2 3 1 2 4 5 5 1 4 2 3 3 3 2 2 2 - - - - - - - - _b._ 21 32 12 24 34 34 22 12 23 12 52 31 33 12 23 13 24 25 15 14 32 23 43 61 -- -- -- -- -- -- -- -- _c._ 22 3 4 35 32 83 22 3 3 31 3 2 33 11 3 21 38 45 52 52 2 4 33 64 -- -- -- -- -- -- -- -- _d._ 30 20 10 22 10 20 52 12 20 50 40 43 30 4 6 22 40 17 24 13 40 23 30 44 -- -- -- -- -- -- -- -- _e._ 4 5 20 12 12 20 10 20 30 3 40 4 11 20 20 10 30 20 4 1 23 7 2 20 2 40 23 40 11 10 30 20 20 10 11 20 22 30 25 -- -- -- -- -- -- -- -- _f._ 19 9 9 14 2 19 24 9 4 13 9 14 13 12 13 13 9 14 17 23 13 15 15 34 12 25 26 29 18 19 25 28 18 39 -- -- -- -- -- -- -- -- _g._ 13 13 9 14 12 9 9 13 12 9 14 24 23 19 19 29 9 9 13 21 28 26 26 14 8 8 29 23 29 16 15 19 17 19 19 22 -- -- -- -- -- -- -- --
