I have two columns in tableau "Started_time" and "ended_time", they are both in "date/time" format, when i try to calculate the "total duration" from these two columns it always pulls up data as a string.
My goal is to caculate the AVG time in "total duration" and when i try to do a caculation with this newly calculated column "total duration" an error pops up "AVG cant do a calculation on a string".
[enter image description here]
I dont know if I should go back to SQL and change the data type to float???

Your second two images are the same (Started Time). Double check that both are in the Date/Time format. For total duration, create a Calculated Field and try using the DATEDIFF function:
DATEDIFF('month', [Started_time], [ended_time])
Change the interval (substitute month with years, weeks, days, etc.)
