For the representation of the confidence interval and statistical data specifications, the
accuracy with which the results are calculated can be specified. The confidence level or
significance level is set by default to 95%.

The values for limit of detection, limit of quantification and detection capability can be viewed
by pressing and tapping the entry
“Statistical data” (see Figure 40).

When creating calibration curves, outliers can occur due to errors in the preparation of the
solution and measurement, and these lead to a widening of the confidence interval. There
are two ways to handle outliers. One way would be to exclude outliers from the calculation by
deselecting the corresponding measured value from the list. The calibration line is then
automatically redrawn. The confidence interval is much narrower. This way, any arbitrary
measurement point can either be excluded from the calculation or be included again.
