## Linear Regression and the Calibration Curve:

This section outlines the use of linear regression techniques and correlation coefficients in determining the calibration curve for a given instrument, method, sample, and analyte. This includes procedures for dealing with outliers in the calibration data, and for estimating the uncertainty associated with sample concentrations determined using the calibration curves. Examples of how to perform all of the required analyses in Excel™ are included throughout, and build on the previous exercises in the section on Excel™ Basics.
