實驗研究（experimental research）是一種通過主動操縱變量并觀察其影響來驗證因果關系的科學方法。其核心特征是在受控環境中建立實驗組與對照組，通過隨機分配參與者并排除幹擾因素，探究自變量（如藥物劑量、教學方法）對因變量（如治療效果、考試成績）的直接作用。
該方法在多個學科中廣泛應用：
實驗研究的科學價值源于其可重複性和客觀性，如2024年《新英格蘭醫學雜志》發表的抗抑郁藥三期臨床試驗，通過多中心雙盲實驗驗證了藥物有效性（參考來源：NEJM官網）。這種方法通過建立明确的因果鍊，為制定科學決策提供實證基礎。
實驗研究（Experimental Research）是一種系統性的科學方法，主要用于探索變量之間的因果關系。以下是其核心要點：
實驗研究通過人為控制或操縱一個或多個自變量（Independent Variable），觀察其對因變量（Dependent Variable）的影響，目的是驗證假設并确定因果關系。例如，在藥物研究中，研究人員可能控制藥物劑量（自變量）來觀察患者症狀改善情況（因變量）。
若需進一步了解具體實驗設計（如雙盲實驗、準實驗設計等），可提供更多背景信息以便補充說明。
