Help With Complex Standard Deviation
I have a table of data, like the below sample data and trying to write a measure from the parent table for Item ID. I need to calculate Standare Deviation based on the individual Plan ID, where S...
There is not enough data to make this statistically significant. How many rows are in your actual data?
This is just sample data. Each plan can have 1 to n rows and each Item ID can have 1 to n plans. Actual data is currently about 11,000 rows, but varies month-to-month. Ultimately, I need a value to indicate whether month-to-month hours are nearly the same, by plan, or have significant variability, where higher variability between months of the same Plan ID and for the Item ID is a good thing, where little or no variability is not good.
