): The average. This is your best estimate of the "true" value after multiple trials. This measures precision . A low means your replicates are tightly clustered; a high means your technique is inconsistent.

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

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

): 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: A low means your replicates are tightly clustered;

Analytical chemists use these tests to determine if a difference in results is "real" or just a fluke of random error.
