Variance(Geometric)

Var(X)=1-pp2
Success Rate

The variance of a set of numbers is the measure of how spread out they are. A variance of zero indicates that there is no variance which means all of the values are the same. Variance can never be represented with a negative number. The higher the variance the more spread out the values in the data set are.

Variables:

  • p = Success Rate
  • q = Failure Rate (Calculated as 1-p)
  • Equation:
  • 1-pp2
