it sounds like a
you havejust the difference of two numbers. Unless you have any kind of distribution that tells you about the variability of the difference between two decades I think you cannot determine a confidence interval. Or maybe I misunderstood.

Subject: [ferret_users] shading 95% significance
Dear Ferret users,
I have gridded nc data for the years JJAS 2001-2010 and 1991-2000.
I am subtracting (2001-2010) minus (1991-2000), I am getting the difference at each grid.
What I have to do is only highlight the difference which is statistically significant at 95%?
Any help will be appreciated.
