Abstract
Although the moving scale, fixed pointer, type of indicator is undesirable for normal use, occasions sometimes arise when it is appropriate, or its use is unavoidable. In one situation of this nature a dial required markings that would designate a quadrant on one side of 0 as North, and the other side as South. Another dial required markings on one side of 0 as Plus, and the other side as Minus. In the absence of specific information covering this problem, an experiment was designed which would supply the necessary information. A naive population of 40 randomly selected, male, senior high school students was used. Results showed that the right side of the moving scale should be marked N or + and the left side S or —. Peripheral information disclosed correlation between score obtained and scholastic performance.
