science-discipline-methods

Use when a research question is still a question rather than a plan — when you know the field but not which study design the field accepts, how many samples it demands, which measurements count as evidence, or which software is standard; also use when a review came back saying the design cannot answer the question, when you are switching fields or advising a student in an unfamiliar one, when two supervisors disagree about method, or when you need to know what reviewers in that field attack first before you commit months to a protocol.

# 学科方法库:先定设计,再谈统计

## 这一层解决什么问题

一个研究生最常见的卡点不是「不会做统计」,而是**问错了问题类型**。

他手里有一个现象、一份数据、一个想说的话,但不知道这个领域**用什么方式把现象变成证据**。
心理学靠随机分配与操纵检查,经济学靠外生变异与平行趋势,化学靠表征链,材料靠批次与标准,
机器学习靠多种子与强基线——同样是「证明 A 影响 B」,各领域要求的证据形态完全不同。

所以这一层的产出不是结论,是**这个领域公认的走路方式**:
能问什么、用哪个设计、要多少样本、量什么、跑什么方法、装什么软件、审稿人先打哪里。
