Abstract
To give reliability to statistical data on samples as discrete materials, a required sample-number determination device includes: a required sample number for each class acquisition unit configured to acquire a required sample number for each class Nby the following Equation (1) based on a proportion P{circumflex over ( )}, that is a ratio of the number of samples in each class to the number of the samples in the population; a temporary required sample number acquisition unit configured to acquire a temporary required sample number N, which may be a maximum value among the required sample numbers for each class N; and a required sample number determination unit configured to determine the temporary required sample number Nas a true required sample number when the sample number reaches the temporary required sample number Nor more, in Equation (1), ξdenotes a constant for accuracy that is set for each class, Kis a constant depending on set reliability, and i as indices denotes a class number assigned to each class.
