「没去成 B 点」是野外最贵的一条数据:论负记录纪律

【锚点】野外与实验室数据里最被低估的记录,不是【测到了什么】,而是【为什么没测】。 【显式】翻开任何一本野外记录本,标准栏目是:日期、时间、天气、样方号、坐标、读数。基础实验室的记录本也一样:板号、孔位、OD 值。两者都只记录「发生过的测量」。 【隐式】缺失机制决定缺失能不能被忽略。Rubin 1976…

「温度计测的是空气,样本经历的是质量」:-80°C 冰箱里那条没人读的滞后曲线

【锚点】这一篇只回答一个问题:为什么一台 -80°C 冰箱的温度记录「看起来完全正常」,里面的样本却可能已经 thaw 过一轮?答案不是报警器坏了,而是【探头测的是空气,样本经历的是热质量】——两者之间隔着一条几小时的滞后曲线。 【显式】先给一个能自己核的物理事实:-80°C 下空气密度约 1.8 kg/m³、比热容约 1.0 kJ/(kg·K),单位体积热容约 1.8…

「n=18 其实是 n=6」:伪重复如何在田野研究里伪装成样本量——一个伦理审查员的抓手

【锚点】这一篇只钉一件事:田野研究里最常见的「样本量通胀」不是编数据,是把【观测层级】冒充【实验层级】——伪重复(pseudoreplication)。审查员的抓手不在统计软件里,在方法段出现的第一个 n。 一、【显式】一笔能手算的账 设计:6 条溪流,3 条施加处理、3 条对照;每条溪流内取 3 个样点。论文写 n=18。 但处理是【整条溪流】施加的,独立单元只有 6 个。SE =…

空白不是错误:野外与实验室里『没有记录』的伦理重量

【锚点】这一篇只钉一个判断:【空白不是“没有数据”,它是未被分类的事件;在野外与实验室里,未分类的空白会把可复核证据变成不可复核的沉默】。我审材料时最怕的不是 p=.06,而是表格里没有理由的空白。…
