CORE DEFINITION
The Z-score, or standard score, is computed as the observed value minus the mean, divided by the standard deviation, and it states how many standard deviations a value sits from the mean. The Altman Z-Score is a separate financial model that predicts the probability of corporate bankruptcy. Together they standardize relative position, converting data of different units and scales into comparable standard scores.
SCAFFOLDING EFFECT
Reduce cognitive load
- Always standardize before comparing: convert two different scales onto one single common axis. - Read the true relative position: state exactly how far a value sits from its own average. - Use Altman for credit risk: score a firm's real bankruptcy risk, not just a data point.
Anchor fast decisions
The Z-score, computed as the value minus the mean divided by the standard deviation, standardizes a datum into a relative position that is free of its original unit and comparable across sources. The Altman Z-Score weights several financial ratios into a sum that predicts bankruptcy probability, where a lower Z means greater danger, and it is the Z-score idea engineered for credit risk.
