QoQ Sales Decile Within Category

[Turambar]

I’m having trouble figuring out how to do this. I want a measure that returns the decile for each item within a given product category based off of [Current QoQ]. The QoQ value will be negative for a fair number of items. Any help would be greatly appreciated.

Hi @Turambar ,

To calculate the decile, you can use the PERCENTILEX.INC function, which returns the percentile of the expression calculated for each row in the table.The INC function returns the number that specifies the percentile. For example, if I have the numbers 0 and 100 in my dataset, the 20th percentile value would be 20. the 50th percentile value would be 50, the 70th percentile value would be 70, and you could calculate what the 100th percentile value would be.

If you write an expression to calculate the 70th percentile value, this also provides the seventh upper decile.

Rank = PERCENTILEX.INC(<table>, <expression>,.70)
