Data Mining Hacker News: Front vs. Back
Really nice work David, good job.<p>One suggestion: For each important conclusion try to have at least one sentence that is understandable by a business exec.<p>For example at first glance it looks like time of day may be significant, then you conclude:<p>"Because the p-value is greater than the alpha value, we fail to reject the null hypothesis that the two nominal categories are independent."<p>By adding after this something like "Therefore submitting articles at a certain time of day is not an effective strategy to achieve front page visibility.", your post gains accessibility.<p>This is not a nitpick.  The idea is to make sure the full power of your analysis is felt across a broad section of readers.  Even if you send to tech people, these things often find their way to a wider audience.
