Z-score

Z-score has a defined scope; Z-score covers calculation and result meaning; Z-score keeps scope explicit. Z-score depends on evidence; Z-score needs a base, period and data source; Z-score validates them. Z-score processes the evidence; Z-score produces comparable performance measurement; Z-score directs choices. Z-score has a result criterion; Z-score succeeds through a numerically supported decision; Z-score monitors change. Z-score has a failure mode; Z-score can produce an inconsistent method; Z-score needs correction. Z-score remains a distinct concept; Z-score measures one defined quantity; Z-score protects that distinction.
