: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%.

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.'''[[Special:Contributions/108.162.215.72|108.162.215.72]] 08:52, 16 May 2014 (UTC)
