Move a number.动一个数字。
Read what the chart will let you claim.看这张图允许你说什么。

Methods Explorer is a set of short labs. Each page is one decision and one chart. You move a slider, the chart updates, and the sentence under the chart says what changed.方法探索是一组短实验。每一页是一个决定，和一张图。你移动滑块，图就更新，图下的句子说明变了什么。

The mistake each page is built to catch is reading the chart as the decision already made. A pay gap can be family savings, not the subsidy. A workshop can look helpful because the stronger students signed up. A clinic notice can fill one faculty and never reach the other. A curve can fit this year’s 24 districts and miss next year’s.每一页要拦住的错误，是把图当成决定已经做出。工资差距可以是家里的积蓄，不是补贴。工作坊可以看起来有用，只因为成绩更好的学生报了名。诊所通知可以传满一个学院，却到不了另一个。一条曲线可以贴住今年的 24 个区，却错过明年的。

• Causal因果 Is the pay gap the subsidy?工资差距是补贴吗？ 300 workers and a subsidy. 80 students and a workshop.300 名工人和一项补贴。80 名学生和一门工作坊。
• Networks网络 When do Arts and Engineering stop talking?文学院和工程学院何时不再说话？ Who talked last month. Whether a clinic notice crosses faculties.上个月谁和谁说过话。诊所通知会不会跨学院。
• Machine Learning机器学习 Will this year’s curve work next year?今年的曲线明年还管用吗？ 24 districts, a penalty, four faculties, and 12 new interviews.24 个区、一个惩罚、四个学院，和 12 份新访谈。
• Text as Data文本作为数据 When do two headlines count as the same claim?两则标题何时算同一主张？ Two headlines, nine clippings, and a map of words.两则标题、九行剪报，和一张词的地图。

Short paths短路径

A path opens the labs in a set order, with the sliders already placed.一条路径按固定顺序打开实验，滑块已经放好。

• Path路径 Overfitting journey过拟合之旅 A straight line, a gentle curve, then a curve that bends to every district.先一条直线，再一条缓弯，然后一条弯向每一个区的曲线。
• Path路径 Three pictures三张图 The subsidy with no effect, no talks across faculties, then a very flexible curve.补贴没有作用、学院之间没有谈话，然后一条非常灵活的曲线。
• Path路径 Balance, then bridges先平衡，再看桥 A loose match, a tight match, then the clinic notice with and without cross-faculty talks.先宽松配对，再严格配对，然后看有没有跨学院谈话时的诊所通知。
• Path路径 Shrink the fit把拟合收一收 A curve that bends to every district, then the same fit with the slopes pulled in.一条弯向每一个区的曲线，然后同一条拟合把斜率往回收。
• Path路径 Counts, clusters, coordinates计数、分组、坐标 Word counts, then folders for nine clippings, then words placed on a map.先数词，再给九行剪报分文件夹，然后把词放到一张图上。
• Path路径 Summarize, then compare先概括，再比较 Two headlines, a map of their words, then a match on one score.两则标题、一张词的地图，然后在一个分数上配对。
