讨论 Discussion “这就是为什么我们是特别的！” “That’s why we are unique!” 实验严格单一变量 Sites are replicated 16S rRNA 基因文库 Culturing-independent 讨论 Discussion 问答和讨论 QA 问答和讨论 QA 谢谢大家！ Thank you! 各果园其他微生物的分析 Genera shared across all orchards 补充 Supplements 稀疏曲线 Rarefaction curves of the sequenced clones for each orchard 补充 Supplements 开场白，大家好之类的~ 有心情的话可以加一点暖场段子什么的哈哈~今天我们要聊的东西，和苹果有关： ） * 介绍文章题目及文章出处：PLoS ONE期刊，2012年发表 * 介绍组员 * 介绍Presentation的内容 * 现在进入第一部分：一些基本知识的回顾以及实验背景的介绍 * * 下面进入第二部分：实验的设计，包括方法啦材料啦什么的 * 接下来是第三部分：实验的结果 * 学生t检验：八年制《医学统计学》教材P80 用于determine if 2 sets of data are significantly different from each other. 2. 双尾检验：八年制《医学统计学》教材P80 The two-tailed Student’s t-test is a statistical test used in inference, in which a given statistical hypothesis, H0 (null hypothesis), will be rejected when the value of the test statistic is either too large or too small. 与单尾实验相对one-tailed test。 3. P值：八年制《医学统计学》教材P97 P0.05称“不显著”；P=0.05称“显著”；P=0.01称“非常显著” P=0.05时，认为数据有统计学意义 * 学生t检验：八年制《医学统计学》教材P80 用于determine if 2 sets of data are significantly different from each other. 2. 双尾检验：八年制《医学统计学》教材P80 The two-tailed Student’s t-test is a statistical test used in inference, in which a given statistical hypothesis, H0 (null hypothesis), will be rejected when the value of the test statistic is either too large or too small. 与单尾实验相对one-tailed test。 3.
