WebApr 11, 2024 · Here the mean, median, and standard deviation values are reasonable but the range of residuals is high overall, likely due to fitting issues in peaks and valleys as seen in Figure 7. An offset to the Salta DEM was expected, due to differences in the vertical reference system, however the ground photons fit it the best, except for beams GT2R … WebFeb 8, 2024 · For example, the probability of the population mean value being between -1.96 and +1.96 standard deviations (z-scores) from the sample mean is 95%. Accordingly, there is a 5% chance that the population mean lies outside of the upper and lower confidence interval (as illustrated by the 2.5% of outliers on either side of the 1.96 z-scores).
