### What is CV in project management?

CV is a term that is used while measuring project
performance.
CV stands for Cost Variance
Cost variance (CV) - This is a measure of cost
performance in terms of deviation of reality from the plan, and it
is obtained by subtracting the actual cost (AC) from the earned
value (EV), as shown in the formula here:
CV = EV - AC
EV = Earned Value
AC = Actual Cost

### What the difference between planned value and earned value?

Planned Value is the authorized budget assigned to the scheduled
work to be accomplished for a schedule activity or a work breakdown
structure component Earned Value is the value of completed work
expressed in terms of the approved budget assigned to that work for
a schedule activity or work breakdown structure component.

### Distinguish between mean deviation and standard deviation?

The mean deviation for any distribution is always 0 and so
conveys no information whatsoever.
The standard deviation is the square root of the variance. The
variance of a set of values is the sum of the probability of each
value multiplied by the square of its difference from the mean for
the set.
A simpler way to calculate the variance is
Expected value of squares - Square of Expected value.

### What is variance?

The variance of a random variable is a measure of its
statistical dispersion, indicating how far from the expected value
its values typically are (Wikipedia 2006). The variance of a
real-valued random variable is its second central moment, and it
also happens to be its second cumulant (Wikipedia 2006). The
variance of a random variable is the square of its standard
deviation (Wikipedia 2006).
Variance is the difference between what is expected and the
actuals. it is the difference between "should take" and "did take".
The deviation from the actuals is called variance. Variance can be
of two types positive and negative.

###### Asked in Statistics

### Why not simply use the mean value of the regressand as its best value?

Variance" is a mesaure of the dispersion of the probability
distribution of a
random variable. Consider two random variables with the same
mean (same aver-age value). If one of them has a distribution with
greater variance, then, roughly
speaking, the probability that the variable will take on a value
far from the mean is
greater.
