Standard Deviation - associating the measure

Greetings,

If anyone has successfully used the standard deviation summary function in Impromptu, please respond and I'll detail my problem.

In summary, I have a query that reports event data for a call centre. I want to be able to report the standard deviation of each agent's value from the mean of all the centre agent's values. If I associate the standard deviation measure by agent, all values are zero (I'm guessing that represents a comparison of the agents value to that same agents average value, ie. the same one). If I associate the measure by CentreName, I get a value, but it's the same for every agent in that centre so I've no idea what it is supposed to represent.

I noticed that similar past threads had no useful information to offer:
thread401-929753 (Oct-04)
thread401-1123578 (Sep-05)
so I'm wondering if this is a useful/used functionality in Impromptu 7.1 or not.

Interestingly, I had some success with a quartile summary function based on Impromptu's percentile function, which successfully does the comparison across the array of agent values, and that measures is associated by agent, so I can't quite figure out what might be wrong.

regards,
Doddy
