Use the Statistics pane to view information related to the reproducibility of an analysis. Each row of the table
summarizes information, such as the average and standard deviation for a group of related peaks, from the same
analyte that would be expected to have the same response.
Description
Label
The row number.
Row
The name of the analyte.
Component Name
When samples are grouped by actual concentration, this column shows the
concentration. When samples are grouped by sample name, this column shows the
sample name.
Sample Name/Actual
Concentration
Shows m of n where n is the total number of samples at the actual concentration (or
with the same sample name) and m is the number of these samples used for the
calculations. Samples are not used if the corresponding peak could not be integrated
or if the Used field has been manually cleared.
Num. Values
The average of the used samples.
Mean
The standard deviation of the used samples.
Standard Deviation
The co-efficient of variance expressed as a percentage: 100 * (Standard Deviation) /
Mean.
Percent CV
The mean value divided by the actual concentration expressed as a percentage: 100
* Mean / (Actual Concentration). This field is shown only when grouping by actual
concentration, not when grouping by sample name.
Accuracy
The individual values for the samples are shown in additional columns. If the
corresponding sample could not be integrated, then N/A is shown. If the Used field
has been manually cleared, then the value is shown with a strikethrough.
