Used to compare the precision (variances) of two different methods. It tells you if one method is significantly more "reproducible" than another.

): 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. Statistical Methods in Analytical Chemistry (Ch...

Analytical chemists use these tests to determine if a difference in results is "real" or just a fluke of random error. Used to compare the precision (variances) of two

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. This is your best estimate of the "true"

A method to find the "best-fit" line ( ) for your calibration standards. Correlation Coefficient ( R2cap R squared

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