Analytical QC Statistics
Summarize replicate precision (mean, SD, %RSD, confidence interval), test for an outlier with Grubbs' test, and check spike recovery and percent error.

G = 1.47 vs. critical G = 1.89 (n = 6). G does not exceed the critical value, so the most extreme point is within the expected spread.
