How to properly do average as New Column

[jtcm4568]

Hello!

It's me again....lots of questions as I figure this all out.

I have a table full of information about the number of times someone answered the phone, and how many seconds that interaction took. It takes the following form:

DateTime	Group Name	Number of Calls	Total length of calls in seconds
2021-01-01 08:00:00	GroupA	46	1,080
2021-01-01 08:00:00	GroupB	412	7,211
2021-01-01 08:30:00	GroupA	12	300

I first created a new Measure:

AverageHandleTime = DIVIDE(SUM([Total Length of Calls]),SUM([Number of Calls]),0)

That works wonderfully...but I just get the number of seconds, and I can't seem to find a way to represent that as a timestamp.

According to a few resources I found online, I have to create a 'Duration' column in my table. I've done that, as structured below:

Date	Group	Number of Calls	Length of Time	Average Call Length	Duration of Avg Call Length
2021-01-01 08:00	GroupA	46	1,080	(1,080)/(46)=23.47	00:00:23
2021-01-01 08:00	GroupB	412	7,211	17.52	00:00:18

Now, however, if I put the numbers into a column chart, in order to get a "reasonable" number for my Y axis, I have to do an Average (of my Average). This feels wrong.

Is there an easier/better way to do duration that I'm missing? Or a better way to crack this nut?

Thanks!

Josh

@jtcm4568 , You should create a measure on top of this measure AverageHandleTime, and use that

time(quotient([AverageHandleTime],3600) , quotient(mod([AverageHandleTime],3600),60), mod(mod([AverageHandleTime],3600),60))

This was brilliant, and for some reason, this kind of solution came up in exactly zero of my searched for how to figure out duration as a measure. Thank you!
