why is it necessary to take the square root of the sum of the activity variance to determine the standard deviation of the project?
The units of data that corresponds to a certain activity in Project Management, is not the same as its units of variances. This happens owing to the fact that in the calculation of the variances in an activity, the differences are squared. Therefore the unit value does not remain the same. Therefore, once the standard deviation is found out by taking the square root of the sum of the activity variance, it becomes feasible to assign the units to its data set in given Project.

What is the relationship between the variance and the standard deviation? Multiple Choice Variance is the square root of the standard deviation. There is no constant relationship between the variance and the standard deviation. Variance is the square of the standard deviation. Variance is twice the standard deviation.
