金香蕉探险：只有成功者的地图可靠吗？Golden Banana: Can We Trust a Map Made Only by Returners?
给返回报告找回出发次数这个分母，用三次探险预算补证据，并准确说出数据尚不能支持的结论。Recover departure denominators, spend three expedition tokens gathering evidence and state what the data still cannot establish.
先在纸上猜结果，再按按钮检验。Predict on paper before checking with the buttons.
课堂版使用固定任务卡练习信息不完整，不模拟原项目的随机迷宫、走失位置或实时多人房间。原游戏的未返回记录不会直接给出陷阱坐标；数据缺失可以由收集过程造成。This classroom version uses fixed mission cards, not the original random maze or live multiplayer rooms. Unreturned reports do not reveal trap coordinates. Missingness can arise from how data are collected.
