听听参观人数上升为什么不能只归功于新展览。

The number of visitors to our town's small museum rose after it opened a new exhibition. The director credited the exhibition, and I was ready to write the same conclusion. Then I learned that the station had also introduced a weekend bus that stopped near the museum.
We compared visitor records by weekday and weekend, but the museum had changed its opening hours at the same time. The available numbers could not separate the effects neatly. The exhibition might have attracted people; the bus might have made the visit easier; both could be true.
Our article described the timing of each change and quoted visitors who gave different reasons for coming. We asked the museum to continue recording how people arrived, while respecting their privacy. We did not turn those answers into a perfect formula.
A trend invites an explanation. It does not hand us one. By placing the bus, the exhibition, and the hours beside the same line on the chart, we made our uncertainty useful instead of hiding it.

镇上的小博物馆推出新展览后，访客数量增加。馆长把功劳归于展览，我也差点写成同样的结论。后来，我发现车站同时新开了一班周末公交，停靠博物馆附近。
我们按工作日和周末比较访客记录，却发现博物馆也在同一时期调整了开放时间。现有数字无法整齐地分离各项影响。展览可能吸引人，公交也可能让到馆更方便，两者可以同时成立。
报道写明每项改变发生的时间，也引用不同访客的到访理由。我们请博物馆在尊重隐私的前提下继续记录访客怎样到来，没有把答案硬套成完美公式。
趋势会引人寻找解释，却不会自动交出唯一答案。把公交、展览和开放时间并列放在同一条数据线旁，我们让不确定性变得有用，而不是把它藏起来。
