Q: Task duration mean
What is the difference between duration mean and duration mean (statistical results)?
A: When you see list of columns of tasks you can find two sets of columns "Duration Mean" and "Duration Mean (statistical results)". List of columns can be accessed by right click to header in each task view, for example in Gantt Chart view. Then you can select "Insert Column Before" or "Insert Column After". You will be list of columns under "Field Type" drop down list.
Results for column "Duration Mean (statistical results)" is calculated as a mean of a difference between start and finish time on each iteration of Monte Carlo simulations. Results of column "Duration Mean" is calculated as Mean Finish time minus Mean Start Time. These results are different by definition. In most cases the difference is insignificant. However in avoid a confusion we recommend using "Duration Mean". "Duration Mean" is used for duration of whole project in Project Summary view.
