• 相関そうかんCommon
  noun, suru verb, intransitive verbCovers correlation as a concept or measure, especially in statistics and technical discussion. It is concise and works in attributive and compound-like uses, making it the default choice for 'correlation' in most contexts.
• 相関関係そうかんかんけいCommon
  nounAlso means correlation, but as a full noun it emphasizes the relationship itself—two or more things being interrelated or intertwining. Use it when saying clearly that a correlation exists between things, e.g. in explanatory or analytical prose.
