Table A2.

Analysis of variance of the data shown in Table A1. Note: 1) the Standard Error based on the main effect of sample Point is identical to signal-plus-noise estimate from Table A1, 2) the Standard error based on the combined effects of Sample and noise (the interaction term) is identical to the noise estimate derived from the column variances of Table A1 (i.e., equation A1).
