Abstract: Suitability of determination standard value for intermediate inspection is determined. A correlation between measured values X for intermediate inspection and measured values Y for final inspection is derived. For each of calculation target points on X-axis, a distribution pattern of measured values Y is specified for measured value Xn of the point based on the correlation, and probabilities of a range determined to be non-defective by determination standard value of final inspection and a range determined to be defective that are included in the distribution are calculated. For each of the ranges of measured values X determined to be non-defective and defective based on the determination standard value of the intermediate inspection, a degree of consistency and a degree of inconsistency between results of inspections are determined using the probabilities. Suitability of the determination standard value is determined based on the two degrees.
