Reducing the measuring interval
Reduce the measuring interval to find the interval where the fit is linear.
Sometimes it is possible to reduce the measuring interval to a smaller range that is still useful.
-
On the Analyse-it ribbon tab, in the
Statistical Analyses group, click Adjust Interval.
The measuring interval drop-down lists show.
- In the Measuring interval drop-down lists, select ≥ 1 and ≤ 5.
-
Click Recalculate.
The analysis report updates.
The linearity plot differences now lie within the allowable nonlinearity of 0.2 mg/dL. Therefore, the method is declared as linear within 0.2mg/dL between the reduced interval 4.65 and 15.4 mg/dL.
