2.5 Significance Testing To determine the regions and time periods where trends are significantly different, we consider the spread of the ensemble members as a normal distribution. To test if the distributions are significantly different, we calculate the Z statistic and use 95% significance (Z ≥ 1.96) as a threshold, where: is the ensemble mean from each simulation. 𝝈 is the standard deviation of each ensemble member divided by the square root of the number of ensemble members.
