Abstract
DURING a recent investigation on electron gun systems which involved the collection of numerical data—the measurements of a certain distance—the problem arose as to how many data it was necessary to collect in order to achieve sufficient accuracy in the final result, which, in this case, was ± 2 percent. Use was made of the formula : where α is the most probable error of the arithmetic mean M, of a series of n observations x1, x2, etc.
