APPENDIX 1. TABLES FOR FACILITATING STATISTICAL WORK. A. CALCULATING TABLES. For heavy arithmetical work an arithmometer 18, of course, invaluable ; but, owing to their cost, arithmetic machines are, as a rule, beyond the reach of the student. For a great deal of simple work, especially work not intended for publication, the student will find a slide-rule exceedingly useful : particulars and prices will be found in any instrument maker's catalogue. A plain 25-cm. rule will serve for most ordinary purposes, or if greater accuracy is desired, a 50-cm. rule, a Fuller spiral rule, or one of Hannyngton-pattern rules (Aston & Mander, London), in which the scale is broken up into a number of parallel segments, may be preferred. For greater exactness in multiplying or dividing, logarithms are almost essential : five-figure tables suffice if answers are only desired true to five digits ; if greater accuracy is needed, seven-figure tables must be used. It is hardly necessary to cite special editions of tables of logarithms here, but attention may perhaps be directed to the recently issued eight-figure tables of Bauschinger and Peters (W. Engelmann, Leipzig, and Asher & Co., London, 1910; vol. i. containing logarithms of all numbers from 1 to 200,000, price 18s. 6d. net.; vol. ii. containing logs. of trigonometric functions). If it is desired to avoid logarithms, extended multiplication tables are very useful. There are many of these, and four of different forms are cited below. Zimmermann’s tables are inex- pensive and recommended for the elementary student, Cotsworth’s, Crelle’s, or Peters’ tables for more advanced work. Barlow's tables are invaluable for calculating standard-deviations of ungrouped observations and similar work.
