# What is the Altman Z-Score?

The Altman Z-score (or simply, "Z-Score") is a statistical measurement of one variables relationship to the mean (average) of a group of values. More specifcally, the Z-score states the number of standard deviations a variable lies from the mean of the group of values. A zero Z-score indicates that the mean of the group and the value being tested is identical. A one or negative one Z-score indicates that the value is one standard deviation from the mean. A positive one indicates that it is one standard deviation above, while a negative one indicaes that it is one standard deviation below the mean. Z-scores are measures of an observation's variability and can be put to use by traders in determining market volatility. The Z-score is more commonly known as the Altman Z-score. The Altman Z-Score is the formula, consisting of five fundamental ratios, used to determine the financial condition of the company and probability for bankruptcy.

Hence, it can be said that the Altman Z-score formula predictions are considerably accurate. However, it is not an absolute formula, thus, must be used in parallel with a qualitative analysis of the business for more accurate predictions.
