Functions used when calculating student results
The following Synergetic functions are used when calculating student results. Similar functions are grouped together with variations related to either the:
- Class or subjects. A class function only operates on the selected class results while a subject function operates on all of the classes using the selected assessment code.
- HighLow or LowHigh. The function used depends on the order of the assessment area we are working with. For example, we would use:
- a HighLow function with a weighted average as we want the highest results first
- a LowHigh function with a ranking as we want the results for the lowest ranked students (that is, the top students) at the top.
They are used on the Formula sub-tab of Subject Assessment Maintenance. See Subject Assessment Maintenance - Area tab - Formula sub-tab.
Formula | Description |
---|---|
@sfAvgClass / | Average the selected student results using the specified class or assessment area. The results are averaged based on the students either:
|
@sfCentileClassHighLow / | Students can be ranked by their class or subject and placed in any of the 99 numbered points that divide an ordered set of scores into 100 parts.
Use the LowHigh functions if you are using an intermediate field such as Ranking as the 'assessment area' in the formula. This will ensure that the top ranked students continued to be displayed first. See Adding a decile or similar formula to student results. |
@sfDecileClassHighLow / | Students can be ranked by their class or subject and placed in one of ten (decile) equal parts, so that each part represents a tenth of the sample. See Adding a decile or similar formula to student results. For the HighLow functions, the:
Use the LowHigh functions if you are using an intermediate field such as Ranking as the 'assessment area' in the formula. This will ensure that the top ranked students continued to be displayed first. |
@sfMarkToGrade | Convert a mark into an alpha grade. That is, A, B, C or D. You specify the assessment area, then the grade and the minimum mark required to receive that grade, using the following format:
You need to use a semicolon to separate the area being marked (here A1) from the grades as in the example. Note: The allocation of alpha grades to marks is also defined in the lookup table luReportResultType. See luReportResultType lookup table in the System maintenance manual. |
@sfMax / | Calculate the minimum and maximum values within multiple assessment areas. |
@sfMaxClass / | Determine the maximum for the selected student results using the specified assessment area. The maximum is identified based on the students either:
|
@sfMedianClass / | Determine the median for the selected student results using the specified assessment area. The median is identified based on the students either:
|
@sfMinClass / | Determine the minimum for the selected student results using the specified assessment area. The minimum is identified based on the students either:
|
@sfQuartileClassHighLow / | Students can be ranked by their class or subject and placed in any of the four quartiles. For the HighLow functions, the:
Use the LowHigh functions if you are using an intermediate field such as Ranking as the 'assessment area' in the formula. This will ensure that the top ranked students continued to be displayed first. |
@sfRankClassHighLow / | Students can be ranked by their class or subject. See Adding a ranking formula to student results. The HighLow functions give the highest result the lowest rank:
Use the LowHigh functions if you are using an intermediate field such as Ranking as the 'assessment area' in the formula. This will ensure that the top ranked students continued to be displayed first. |
@sfStdDevClass / | Calculate the standard deviation for the selected student results using the specified assessment area. The standard deviation calculated can either be for a:
The standard deviation is identified based on the students either:
|
@sfWeightedAverage | Calculate the average for the selected assessment areas, taking into account the weighting factors applied to each. See Adding a weighted average formula to student results. For example, the German A subject assessment includes three areas that are assessed:
|
