Readability of mathematical tables
Abstract
To study the effect of certain typographical variations upon readability of mathematical tables, time in seconds to look up squares, square roots, and cube roots were obtained for six groups of adult Ss reading from five typographically different tables. Eight suggestions are made to achieve effective typographical arrangement: keep pages uncrowded, limited to one set of 50-entry columns, set in at least 8 point type, columns separated by at least 1 pica space without rules, with No. column in bold face, printed on thick enough white mat paper in jet black ink to prevent shadows from reverse of page and ensure maximum contrast.
