Analyzing Data – Quantitative Methods • Plot the candidate method result (x‐axis) vs. the reference method  result (y‐axis) for each matrix. Calculate the slope and square of the  linear correlation coefficient (r 2 ) for each plot.  • Calculate repeatability as the standard deviation of replicates at each  concentration of each matrix for each method. • Calculate the mean difference between the candidate and reference  method transformed results with 95% confidence interval for each  concentration of each matrix.
