DefinitionExperimental data (実験データ) is data obtained by deliberately changing conditions and measuring the results.
ExplanationBecause everything except the changed condition is kept the same, it is easier to confirm whether that condition caused the result. In business, preparing two designs for a Web page, splitting users between them, and comparing their responses is one such method.
AnalogyIt is the same idea as cooking two plates that differ only in the amount of salt and tasting them side by side.
Memory hookThe English word experiment comes from the idea of trying something out, so it is data you get by trying.
