APPENDIX 399 rate into two packs. On this side of the board where you see the ‘ O ’ (pointing to left side of a 12" x 12"’cardboard with an ‘O’ in the upper left hand corner) put all cards which have an ‘ O ’ on them. On the other side, put those that do not have an * O Try it with this pack (handing subject the sample pack of six cards, three with and three without an ‘ O ’). Now do it with this whole pack quickly and carefully. Ready? Start.” (Press stop-watch at the word ‘start ’ and again when subject is finished.) Record: Turn cards face down and sort back into original order according to numbers on the back of each card, counting mistakes in the process. Record as follows: number of test, seconds taken, number of mistakes made. For ex ample, 2; 35 secs., 2 E. Rating: Read following section on rating. All tests are rated ac cording to one of two formulae. In this one we apply formula II. The point of reference is sorting the 50 cards in 25 seconds. RU, or the total number of units in the test is 50 (cards). Ru, or the reference time per unit is .7, i. e., 35 (seconds) -f- 50 (units). E, the number of errors, to be counted double. T, the time. Applying formula II to the above sample record, ( Ru X RU — 2 E ) T = rating, •7 X (50 ~ 4) 35 = .92 C. RATING Because of the multiplicity of varieties of tests and ways of giving them, much confusion has arisen over the methods of rating. Some tests are rated according to the amount done in a given time; others, according to the time taken to complete the entire test others, according to the number of correct and false moves; etc., etc. Because of this variety and subsequent
