Description:
The D'Agostino test of normality is presented by various references as a suitable test for normality for 50 to 1000 measurements.
In ChemStatimplementation, the D'Agostino test can test the normality of data for any parameter for a selected monitoring location, for all background monitoring locations, for all compliance monitoring locations, and for all monitoring locations. Select the monitoring location group from the right-click menu. The selected group should contain at least 50 measurements. Use the right-mouse-click context menu to select the monitoring location group
Dtest can also be used to test for normality of the residuals. From the normality sub-menu on the right-click menu, select Residuals to test the residuals. Select Data to test the actual parameter concentrations for normality.
Use:
To test for normality in data sets with 50 to 1000 measurements. The test can be performed on the selected monitoring location, all compliance monitoring locations, all background monitoring locations, or all monitoring locations.
