VISUAL TITRATION STATISTICS Repeatability Standard Deviation, 1s r and 95 Percent Confidence Estimate Repeatability standard deviation is an estimate of the variability one trained analyst should be able to obtain under favorable conditions (analyzing a sample, with one instrument, within one day).

It is determined for “fresh” samples only. Bias is not determined for “seasoned” samples, since the component concentration level was not determined independently of the test method. Statistically significant biases were found for hypo index, thiosulfate, and sodium sulfite (see the table below) for a “fresh” tank Process ECN-2 Fixer sample. However, the individual biases for hypo index, thiosulfate, or sodium sulfite were judged not to be practically significant.

Recovery Recovery is used instead of bias for “seasoned” samples, since the component concentration level was not determined independently of the test method. It is defined as the calculated mean for the “seasoned” sample with a standard addition of the component minus the mean for the “seasoned” sample, divided by the actual amount of the standard addition. It is expressed as a percentage. The table below show whether or not a recovery is statistically or practically significant from 100 percent.

Recovery<br />
Recovery is used instead of bias for “seasoned” samples, since the<br />
component concentration level was not determined independently of<br />
the test method. It is defined as the calculated mean for the<br />
“seasoned” sample with a standard addition of the component minus<br />
the mean for the “seasoned” sample, divided by the actual amount of<br />
the standard addition. It is expressed as a percentage. The table below<br />
show whether or not a recovery is statistically or practically<br />
significant from 100 percent.<br />
