Zusammenfassung:To provide a data analysis method capable of correctly evaluating a degree of association of characteristics between products manufactured from the same material lot by a different manufacturing line, a data analysis device, and a computer program.SOLUTION: A data analysis method comprises an acquisition step, and an evaluation step. The acquisition step acquires a dataset containing independent data collected in a manufacturing process and not depending on a specific process to be analyzed during the manufacturing process, and dependent data collected in the manufacturing process and depending on the specific process. The evaluation step evaluates relevance between datasets using all independent data and dependent data corresponding to the specific process.SELECTED DRAWING: Figure 8 【課題】同じ原料ロットから異なる製造ラインによって製造された製品間における特性の関連度を正しく評価するデータ分析方法、データ分析装置及びコンピュータプログラムを提供する。【解決手段】データ分析方法は、製造工程において収集されたデータであって、製造工程中の分析対象とする特定のプロセスに依存しない非依存データと、特定のプロセスに依存する依存データと、を含むデータセットを取得する取得工程と、非依存データの全てと、特定のプロセスに対応した依存データと、を用いて、データセットの関連性を評価する評価工程と、を備える。【選択図】図８
