To suppress oversight of a factor in an analysis of a changing factor of observation data.SOLUTION: A data analysis device according to one embodiment includes an acquisition unit, an index value calculation unit, a parent element extraction unit, and an output control unit. The acquisition unit acquires a data element group composed of a plurality of data elements. The index value calculation unit calculates an index value indicating a conditional variation with other data elements of the data element group as to a first data element of the data element group. The parent element extraction unit extracts a parent element that is highly related to the first data element from the data element group on the basis of the index value. The output control unit outputs an analysis result including first information about the first data element and the parent element.SELECTED DRAWING: Figure 2 【課題】観測データの変化要因の解析において、要因の見落としを抑制すること。【解決手段】一実施形態に係るデータ解析装置は、取得部と、指標値算出部と、親要素抽出部と、出力制御部とを含む。取得部は、複数のデータ要素で構成されるデータ要素群を取得する。指標値算出部は、データ要素群のうちの第１のデータ要素について、データ要素群のうちの他のデータ要素との条件付きばらつきを示す指標値を算出する。親要素抽出部は、指標値に基づき、第１のデータ要素と関連性の高い親要素をデータ要素群から抽出する。出力制御部は、第１のデータ要素と親要素とに関する第１の情報を含む解析結果を出力する。【選択図】図２
