Z-score Formula Below you will find descriptions and details for the 1 formula that is used to compute Z-scores when the population mean and standard deviation are known. Standard normal score (Z-score): wherexis the raw score to be standardized,μis the population mean, andσis the popul...
A z-score is defined as the number of standard deviation from the mean. A z-score of 1.5 means that this value 1.5 standard deviations above the mean. If it were -1.5, it would be below the mean. How do you calculate the Z-score? To calculate the z-score, find the mean and stan...

This is because the metric is susceptible to dishonest accounting techniques and can be changed by owners who want to hide or falsify their financial data. As with any ratio, the Z-score should be used alongside other measures to get a clearer picture. FAQS on Z-Score What Is a Z-...

In other cases, the measurement units are meaningful, but you want to see the relative standing. For example, if a baby weighs five kilograms, you might wonder how her weight compares to others. For a one-month-old baby girl, that equates to a z-score of 0.74. She weighs more than ...
Z-score, sometimes called standard score, is a measurement of how many standard deviations a point is away from the mean of its data set. This concept was adapted to the business and finance world by Dr. Edward Altman who used it predict the likelihood t
A Z-Score is a statistical measurement of a score's relationship to the mean in a group of scores. A Z-score can reveal to a trader if a value is typical for a specified data set or if it is atypical. In general, a Z-score of -3.0 to 3.0 suggests that a stock is trading with...
The Altman Z-score is the output of a credit-strength test that gauges a publicly traded manufacturing company's likelihood of bankruptcy.
