  • $\begingroup$ For the word "significance" to apply (in the statistical sense), you'd need some null hypothesis (and hopefully an alternative for which you which you would like to have some power), and some assumptions about the situation (do you have independence, for example)? $\endgroup$ – Glen_b -Reinstate Monica Dec 13 '14 at 23:00
