I have created a measure which calculate the efficiency per week by following formula:
1 - DIVIDE([Hour Spent],[Total available hours])
I have calculated week after week this, now I want the average of these values (13 week i.e. quarter 1) as a result.
| week | group | Hours Spent | Average of Capacity | Efficiency |
| 1 | sales | 214 | 1 | |
| 2 | sales | 4.5 | 552.5 | 0.991855 |
| 3 | sales | 10 | 712 | 0.985955 |
| 4 | sales | 10.5 | 659.5 | 0.984079 |
| 5 | sales | 20.5 | 734 | 0.972071 |
| 6 | sales | 25 | 776.75 | 0.967815 |
| 7 | sales | 32 | 622.5 | 0.948594 |
| 8 | sales | 25 | 493.75 | 0.949367 |
| 9 | sales | 4 | 653.25 | 0.993877 |
| 10 | sales | 11.5 | 715 | 0.983916 |
| 11 | sales | 9.5 | 1051.25 | 0.990963 |
| 12 | sales | 6.5 | 667.5 | 0.990262 |
| 13 | sales | 21.5 | 627.75 | 0.965751 |
| Total | 180.5 | 690.97 | 0.74 |
As we can see at the bottom I am getting .74 , rather than this I am expecting the average of efficiency which should be .9788.
How can we get that value. Please advice and help.
