				<content:encoded><![CDATA[<p>生物学里面，唯一还算有点技术含量，和有点门槛，就是生物统计了，而这也是绝大部分研究者的痛点，有能力的，可以看看nature上面关于统计学的专题讨论，而且主要是应用于自然科学的统计学讨论。</p>
<div dir="ltr"><a href="http://www.nature.com/collections/qghhqm" target="_blank">http://www.nature.com/collections/qghhqm</a></div>
<div dir="ltr">里面有几句统计学名言警句：</div>
<div dir="ltr">
<div>
<div>Statistics does not tell us whether we are right. It tells us the chances of being wrong.</div>
<div>统计学并不会告诉我们是否正确，而只是说明我们错误的可能性是多少。</div>
<div>Quality is often more important than quantity.</div>
<div>数据的质量远比数量要重要的多</div>
<div>The meaning of error bars is often misinterpreted, as is the statistical significance of their overlap.</div>
<div>Good experimental designs mitigate experimental error and the impact of factors not under study.<span style="color: #333333; font-family: arial,helvetica,ＭＳ Ｐゴシック,ＭＳ ゴシック,Osaka,MS PGothic,sans-serif;"><b><br />

</div>
<div>文章列表：</div>
<div>
<div>Research methods: Know when your numbers are significant</div>
<div>Scientific method: Statistical errors</div>
<div>Weak statistical standards implicated in scientific irreproducibility</div>
<div>The fickle P value generates irreproducible results</div>
<div>Vital statistics</div>

<div>Points of Significance: Bayes' theorem</div>
<div>Points of significance: Bayesian statistics</div>
<div>Points of Significance: Sampling distributions and the bootstrap</div>
<div>Points of Significance: Bayesian networks</div>
<div></div>
<div>A study with low statistical power has a reduced chance of detecting a true effect, but it is less well appreciated that low power also reduces the likelihood that a statistically significant result reflects a true effect. Here, we show that the average statistical power of studies in the neurosciences is very low. The consequences of this include overestimates of effect size and low reproducibility of results. There are also ethical dimensions to this problem, as unreliable research is inefficient and wasteful. Improving reproducibility in neuroscience is a key priority and requires attention to well-established but often ignored methodological principles.</div>
