What does a CPI value less than 1.0 indicates?
A CPI of 1 means the project is on budget, which is also a good result. A CPI of less than 1 means the project is over budget. This represents a risk in that the project may run out of money before it is completed.
Can the variance ever be negative?
A large variance indicates that numbers in the set are far from the mean and from each other, while a small variance indicates the opposite. Variance can be negative. A variance value of zero indicates that all values within a set of numbers are identical. All variances that are not zero will be positive numbers.

Why is variance positive?
It measures the degree of variation of individual observations with regard to the mean. It gives a weight to the larger deviations from the mean because it uses the squares of these deviations. A mathematical convenience of this is that the variance is always positive, as squares are always positive (or zero).
Can the Z score be negative?
The value of the z-score tells you how many standard deviations you are away from the mean. If a z-score is equal to 0, it is on the mean. A positive z-score indicates the raw score is higher than the mean average. A negative z-score reveals the raw score is below the mean average.
Is median higher than average?
The median is greater than the mean – Math Central. Question from Shawna, a student: If the median is greater than the mean on a set of test scores, The official answer is that the data are “skewed to the left”, with a long tail of low scores pulling the mean down more than the median.
