摘要
A quality variation display device that can surely identify periodic information about quality on a product number basis such as the occurrence of a failure for every prescribed number of products is provided. The device includes a quality data storing database that stores the measurement result of each product measured by a measuring unit in association with the manufacturing order, an interval statistic calculation portion that shifts an interval corresponding to a prescribed number of products by a prescribed shift number of products, obtains a statistic for each of the intervals, and produces a graph representing the statistics in the manufacturing order at equal intervals, and a display portion that displays the graph.
