f we assume the random noise in the simulation is uniform, we can say that if we repeat this simulation over and over again, 95% of the time the value we get will be within 2 standard deviations either way of the average. In other words, there’s about 1 chance in 40 that you will get a value lower than average -2 and 1 chance in 40 that you’ll get a value higher than average + 2 . What range will 95% of your numbers land in
