I agree with the main point of the article, but I&#x27;m somewhat disturbed by the statistical errors and misconceptions.<p>&gt;Few websites actually get enough traffic for their &gt;audiences to even out into a nice pretty bell curve. If &gt;you get less than a million visitors a month your &gt;audience won’t be identically distributed and, even &gt;then, it can be unlikely.<p>What is the author trying to say here?  Has he thought hard about what it means for &quot;an audience&quot; to be identically distributed?<p>&gt;Likewise, the things that matter to you on your website, &gt;like order values, are not normally distributed
Why do they need to be?<p>&gt;Statistical power is simply the likelihood that the &gt;difference you’ve detected during your experiment &gt;actually reflects a difference in the real world.
Simply googling the term would reveal this is incorrect.
