Find anomaly in a series of numbers
<p>I have list of numbers </p>

<pre><code>var nums = new List&lt;double&gt; {1,2,2.4,2.6,1.5,3,1.9};
</code></pre>

<p>The items of the list are assumed to be distributed <em>normally</em>; in the such series I want to filter out <em>anomalies</em> (which can be <code>1</code> and <code>3</code> since they seems to be the <em>most deviated values</em>). I have to work with dynamic series and their values may change, so can't hard code any value in a condition check.</p>
