Median (fld), Median (fld, condFld), Median (fld, condFld, cond)
Basic and Crystal syntax.
Arguments
- fld is any valid database or formula field that can be evaluated by the function.
- condFld is a field used to group the values in fld by.
- cond is a String indicating the type of grouping for condFld. You only specify this argument when condFld is a Date, Time, DateTime or Boolean field. For more information on the valid strings for this argument, see Conditions for summary functions.
Returns
Fractional Number
Action
Calculates the median of the given numeric fields. The median is the middle value in a sequence of numeric values (or the average of the two middle values in an even-numbered sequence of values).
For example:
- You can calculate the median of all the values in a field. For information on this kind of summary, see SummaryFunction (fld).
- You can calculate the median of all the values in the field, within a group (for example, sales grouped by the state that they come from). For information on this kind of summary, see SummaryFunction (fld, condFld).
- You can calculate the median of all the values within a group in which grouping is controlled by changes in a date or Boolean field (for example, sales grouped by the month in which they were made). For information on this kind of summary, see SummaryFunction (fld, condFld, cond).
Examples
The following examples are applicable to both Basic and Crystal syntax:
Median({Customer.LAST YEAR'S SALES})
Returns $29087, where the values of the Last Year's Sales field are $27014, $28000, $29087, $34500, and $48260.
Median({Customer.LAST YEAR'S SALES}, {Customer.REGION)
Groups the Last Year's Sales field by region and returns the median of the Last Year's Sales field per region.
Median({orders.ORDER AMOUNT}, {Customer.REGION}, "monthly")
Groups values in the Amount field by region, then returns the median of the order amount for each region per month.
Note: Using this function in a formula forces the formula to be evaluated at print time.
For more information on evaluation time considerations, see Evaluation Time functions.
