Errors that have a definite cause (e.g., an uncalibrated pipette). These affect accuracy —how close you are to the true value.

The lowest concentration that can be reliably distinguished from the "blank" (noise). Statistical Methods in Analytical Chemistry (Ch...

): Indicates how well your data fits that linear model. In analytical work, we usually look for 5. Limits of the Method Statistics define the "floor" of what an instrument can do: Errors that have a definite cause (e

Analytical chemistry isn’t just about getting a number; it’s about knowing how much you can trust that number. Statistics provide the framework to quantify uncertainty and prove that your results are reliable. 1. Describing the Data (Central Tendency and Spread) ): Indicates how well your data fits that linear model

Expressed as a percentage, this allows you to compare the precision of different methods regardless of the units. 2. Error Analysis: Accuracy vs. Precision
