实验研究（experimental research）是一种通过主动操纵变量并观察其影响来验证因果关系的科学方法。其核心特征是在受控环境中建立实验组与对照组，通过随机分配参与者并排除干扰因素，探究自变量（如药物剂量、教学方法）对因变量（如治疗效果、考试成绩）的直接作用。
该方法在多个学科中广泛应用：
实验研究的科学价值源于其可重复性和客观性，如2024年《新英格兰医学杂志》发表的抗抑郁药三期临床试验，通过多中心双盲实验验证了药物有效性（参考来源：NEJM官网）。这种方法通过建立明确的因果链，为制定科学决策提供实证基础。
实验研究（Experimental Research）是一种系统性的科学方法，主要用于探索变量之间的因果关系。以下是其核心要点：
实验研究通过人为控制或操纵一个或多个自变量（Independent Variable），观察其对因变量（Dependent Variable）的影响，目的是验证假设并确定因果关系。例如，在药物研究中，研究人员可能控制药物剂量（自变量）来观察患者症状改善情况（因变量）。
若需进一步了解具体实验设计（如双盲实验、准实验设计等），可提供更多背景信息以便补充说明。
