* A log scale arranges the data points in a more manageable view so that the effect of all points
can be monitored simultaneously. For this view, select Log Scale Y Axis versus Log Scale X
and not just the log of one axis.

Sample Statistics

Use the Statistics window to view the statistics samples, typically for standards and QCs (quality
controls). The data from each available batch in the Results Table opens in tabular form in the
grid and a row of data is shown for each standard or QC concentration.

View the Statistics for Standards and QCs

When viewing more than one Results Table, statistical information about the standards and QCs
for additional batches in the Statistics window can be obtained. This allows the user to compare
results between batches and look for trends in the standards or QCs.
1. With a Results Table open, click Tools > Statistics.
2. In the Statistics Metric list, select Concentration.
3. In the Analyte Name field, select an analyte.
4. In the Sample Type field, select Standard.
The results are shown.
5. Look at the %CV and Accuracy columns.
The %CV shows the coefficient of variance between the measurements of a single
parameter, for example the area. Accuracy shows how close the plotted point is to
the interpolated value.
