Statistics - Class Statistics tab

You can use the Class Statistics tab to scale student results by result group and class group.

Note: Result group was used before calculations and formulas were developed in Synergetic. Some organisations still use this method using a user-calculation stored procedure.

Tip: Consider using the Formula tab instead. See Subject Assessment Maintenance - Area tab - Formula sub-tab.

Opening the Class Statistics tab

To open the Class Statistics tab:

Open Student Results Maintenance for the relevant class. See Maintaining student results.
Click either the Single Student, All Students or Mark Book tab.
Click .
The Class Statistics tab of the Statistics window is displayed.

Result Groups grid area fields

Field	Description
Result Group	Result group being applied to the results. See Class Maintenance - Result Groups tab.
Group Class	Group class that links the assessments together. See Class Maintenance - Result Groups tab.
OrideType	The override type for the result group. For example: none mean/standard deviation minimum/maximum.
Mean / Std Dev / Min / Max	Mean, standard deviation, minimum and maximum values to be applied when scaling marks.

Class Group Statistics grid area fields

Field	Description
Class	Class code for the selected class.
Num	Numerical result.
Cal Mn	Calibre mean of the results.
Cal SD	Calibre standard deviation of the results.
Adj Mn	Adjusted mean of the results.
Adj SD	Adjusted standard deviation of the results.
Scl Mn	Scaled mean of the results.
Scl SD	Scaled standard deviation of the results.
Diff Mn	Differential mean above the results.
Diff SD	Differential standard deviation above the results.

Override Type area fields

Field	Description
No Override	Select to not perform any overrides.
Mean/Std Deviation	Select to override the mean and standard deviation.
Max/Min	Select to override the maximum and minimum results.

Overridden Values area fields

Field	Description
Mean	Type the new mean to adjust the statistics to.
Std Deviation	Type the new standard deviation to adjust the statistics to.
Min	Type the new minimum result to adjust the statistics to.
Max	Type the new maximum result to adjust the statistics to.

Overall Statistics area fields

Note: These fields cannot be edited. They illustrate the difference between the calibre and the scaled marks.

Field	Description
Mean of Calibre Marks / Mean of Scaled Marks	Mean of calibre marks and scaled marks across all class groups.
SD of Calibre Marks / SD of Scaled Marks	Standard deviation of calibre marks and scaled marks across all class groups.
Diff in above Means / Diff in above SDs	Differential above the means and standard deviation across all class groups.
Max of Scaled Marks	Maximum of scaled marks across all class groups.
Min of Scaled Marks	Minimum of scaled marks across all class groups.
