What is true about the project standard deviation?

It is the average of the individual tasks' standard deviations
It is determined by finding the mode of the project's variances
It is the square root of the sum of the individual tasks' variances
It is identical to the project mean

The correct answer is: It is the square root of the sum of the individual tasks' variances

The project standard deviation is a measure of how spread out the data is from the mean, and it takes into account the variability of individual tasks. Option A, which states that it is the average of the individual tasks' standard deviations, is incorrect because the project standard deviation is not simply the mean of the individual task standard deviations. Option B, which suggests finding the mode of the project's variances, is incorrect because mode is not typically used to calculate standard deviation. Option D, which says it is identical to the project mean, is incorrect because they measure different things - mean measures central tendency while standard deviation measures variability.
