Before complex modeling, you have to understand the "shape" of your results. Mean (

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

The lowest concentration at which we can perform a quantitative measurement with acceptable precision. 6. Confidence Intervals (CI) Before complex modeling, you have to understand the

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. Statistics provide the framework to quantify uncertainty and

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)

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