一个有趣的研究日
小明先做了一个关于午睡的 Experiment，并提出一个 Hypothesis：多睡十分钟，大家就会更开心。他拿起一个 Tool，决定不靠猜测，而是认真做。
首先，他选了一个小 Sample，又发出一份 Survey 和一份 Questionnaire。他还仔细做 Observation，并把每个细节都记录在 Record 里。
接着，他一次只改变一个 Variable，并设置了一个 Control 组。每做完一次 Measure，他就进行 Compare，结果最安静的那组反而笑得最厉害。
小明完成了 Analysis，写下 Conclusion：好的 Evidence 需要 Accuracy，不能只靠强烈意见。等他发起 Interview 时，大家都说下次还想参加他的研究。
Ming started an Experiment about naps and formed a Hypothesis that ten more minutes of sleep would make everyone happier. He grabbed a Tool and decided to trust the process instead of guessing.
First, he chose a small Sample and sent out a Survey and a Questionnaire. He also watched the room with careful Observation while keeping every detail in a Record.
Then he changed one Variable at a time and set up a Control group. After each Measure, he did a Compare, and the quietest group ended up laughing the loudest.
Ming finished the Analysis and wrote the Conclusion: good Evidence needs Accuracy, not just strong opinions. When he asked for an Interview, everyone said they wanted to join his next study.
