422 APPENDIX Rating: Apply formula II. Point of reference is perfect com pletion of 40 units in 160 seconds; RU, 40; Ru, 4 secs.; errors count 2. Apply to sample record above, 4 X (40 - 20) — .oO. IOO G. TYPIST TESTS 1. Order of Procedure: (a) Shock absorber (b) IS (c) 13c (d) 16 (e) 20T3 2. Shock Absorber: As a shock absorber, give subject a type written letter with several glaring mistakes in spacing, punctuation, and capitalization. Ask subject to read this letter and check off the mistakes. This test should be very simple and easy. 3. Pro-rating: The applicant’s desirability is determined by pro-rating the above tests according to the formula: .10 X ri5 .25 X ri3c + .25 X ri6 + .40 X r2oT3 = R. From this it will be seen that the typing test counts much more than any other, viz., 40%, while the context and spell ing tests count 25% each, and the letter substitution test 10%. However, in the case of a new typist, just out of school, who has not yet had time to develop speed on the machine, it is advisable to count the typing test only 25%, and tests 13c, 16, and 15, 30%, 30%, and 15% respectively. Thjs is on the assumption that ability in these tests pred icates a good basis for future ability as a typist. See Chapter VIII. 4. Standards: From .60 to 1.00 shall be recommended; between .50 and .60 shall be recommended for a trial under close supervision.
