To compute all the other z-scores, first, first we click on the cell that contains the formula we want to copy (in this example, B2). Second, we place our cursor over the bottom left corner of the cell until a cross appears. Third, once the cross appears, we double-click the cross and drag it down the column. As we drag the cross down Column B $\begingroup$ There is a ton of information online about the standard score. You may want to consider making your question much more concrete; otherwise, you will just get at most a duplicate of what you can find here. $\endgroup$ โ€“ The original z-score formula intended for public manufacturing companies is shown below: Altman Z-Score = (1.2 ร— X1) + (1.4 ร— X2) + (3.3 ร— X3) + (0.6 ร— X4) + (0.99 ร— X5) The formula above is the most common variation of the Altman z-score, although each model consists of different variables and weighing systems that affect the score.
The formula for calculating a z-score is z = (x-ฮผ)/ฯƒ, where x is the raw score, ฮผ is the population mean, and ฯƒ is the population standard deviation. This formula allows for standardizing scores, making it easier to compare different sets of data. The z-score formula is straightforward and involves simple arithmetic operations.
Step 4: Find the area using the z-score from step 3. Use the z-table. Not sure how to read a z-table? See the video on the z-table page. Step 6: Go to Step 6a to find a probability OR go to step 6b to calculate a certain number or amount. Step 6a Turn step 5โ€™s answer into a percentage. For example, 0.1293 is 12.93%. Skip step 6b: youโ€™re done!
These values correspond to the probability of observing such an extreme value by chance. In the test score example above, the P-value is 0.0082, so the probability of observing such a value by chance is less that 0.01, and the result is significant at the 0.01 level. In a one-sided test, corresponds to the critical value z * such that P(Z > z
