make_dpcust 1



Here is what the above code is Doing:
1. We are creating a new measure called “Quantity Std. Dev”
2. We are using the “count” aggregator to aggregate the measure
3. We are using the “KeyExpression” to define the SQL that will be used to calculate the measure
4. We are using the “make_dpcust” function to convert the standard deviation into a string
5. We are using the “stddev” function to calculate the standard deviation of the “quantityordered” column
