Used to compare a measured mean to a known value, or to compare two sets of means to see if two methods yield the same result.

Instead of reporting a single number, chemists report a range. A 95% Confidence Interval tells the reader: "I am 95% sure the true value lies between X and Y." This accounts for both the mean and the uncertainty of the measurement. Statistical Methods in Analytical Chemistry (Ch...

Inherent fluctuations in any measurement. These affect precision . These errors typically follow a Gaussian (Normal) Distribution , forming the classic bell curve. 3. Significance Testing (The "Decision Makers") Used to compare a measured mean to a
