Those lazy scientists are playing minecraft instead of curing cancer! Lynch 'em! Davidy22[talk] 00:35, 11 January 2013 (UTC)

But I heard that Minecraft cures cancer... Scientists! Investigate! <off: cheers from active group, boos from the control group> 178.99.81.144 19:31, 30 April 2013 (UTC)
You know this experiment isn't conducted properly when you know you're in the control group. Troy (talk) 05:24, 4 March 2014 (UTC)

Um, I take it that whoever explained this comic can't tell the difference between < and >, as the fact that the confidence was changed wasn't mentioned in the article... 76.246.37.141 23:19, 20 September 2013 (UTC)

Yes, I also figured out this today, green is lower than 0.05, on other colors there is just a confidence that it's NOT lower than 0.05. The newspaper did add this remaining 19 panels to 95%. The article is marked as incomplete, it needs a major rewrite.--Dgbrt (talk) 19:12, 3 October 2013 (UTC)

This explanation seems to misinterpret α. α is the chance of rejecting a true null hypothesis, a false positive. The 5% here is α. The correct interpretation of it is that if the null hypothesis is true, there is a 5% chance that we will mistakenly reject it. P in "P<0.05" is the chance that, if the null hypothesis is true, a result as extreme as, or more extreme than, the result we get from this experiment. α is not the chance that, given our current data, the null hypothsis is true. We wish to know what that is, but we do not know.108.162.215.72 08:52, 16 May 2014 (UTC)
