Automatic calculation
I want to create a spreadsheet that will automatically calculate a sum... I
have no idea how to do this... My Telephone section took 1563 calls. All these calls added together took 80:39:43 (HH:MM:SS) Is there any way I can get staff to enter these numbers in to Excel to work out the AVERAGE call length in MINUTES? Any help is much appriciated, though I am virtually clueless when it comes to Excel. Thank you, -- Rob, Teesside, UK |
Assume the times are in column B
C1: = SUM(b:B) and format as [hh]:mm C2: =AVERAGE(B:B) -- HTH Bob Phillips "abfabrob" wrote in message ... I want to create a spreadsheet that will automatically calculate a sum...

Hey there,
Thanks you for the help, but can't get it to work... E.G.

Rob,
Are you saying that B 1 is a call time, and B2 is an other call time? If so, why is B2 not in time, and why is the answer 1:01:00? -- HTH Bob Phillips "abfabrob" wrote in message ...

Bob,
Using your formula, I put my numbers in column B (and what you told me to put in column C) 10:10:00 in cell B1 - this is HH:MM:SS of ALL calls (total time of all calls) 10 in cell B2 - this is how many calls were taken, So 10:10:00 (10 hours and 10 mins), divided by ten calls gives you an average of 01:01:00 (1 hour and 1 min per call). Obviously my figures will be more complicated than this in the real thing. It will be me - not very gopod with Excel.

I have tried this, but get a message saying that the formula contains an error.

Rob,
I see now. The problem is that you are mixing the call times and the calls together, so any formula such that I gave will get confused by them. Put your call times in column B, call numbers in column C, and then use =SUM(A:A)/SUM(B:B) to get the average -- HTH Bob Phillips "abfabrob" wrote in message ... Bob, Using your formula, I put my numbers in column B (and what you told me to put in column C) 10:10:00 in cell B1 - this is HH:MM:SS of ALL calls (total time of all calls) 10 in cell B2 - this is how many calls were taken, So 10:10:00 (10 hours and 10 mins), divided by ten calls gives you an average of 01:01:00 (1 hour and 1 min per call).
