The Altman Z-score equation is calculated by weighting various financial ratios and comparing their sum to a graded scale. The equation looks like this: As you can see, the Altman score weights different profitability and liquidity metrics to arrive at the overall score. This overall score is then compared to the following grading scale.
Z-scores-problem. Nutritionists measured the sugar content (in grams) for 32 drinks at Jake's Java coffee shop. The drinks had a mean of 18 g and a standard deviation of 5 g , and the distribution was roughly symmetric. A Grande Mocha Cappuccino at Jake's Java contains 14 g of sugar. Calculate the standardized score (z-score) for the Grande
Standard Score. The standard score (more commonly referred to as a z-score) is a very useful statistic because it (a) allows us to calculate the probability of a score occurring within our normal distribution and (b) enables us to compare two scores that are from different normal distributions. The standard score does this by converting (in
In a nutshell, the Z-table shows only the probability below a certain z-value, and you want the probability between two z-values, –z and z. If 95% of the values must lie between –z and z, you expand this idea to notice that a combined 5% of the values lie above z and below –z. So 2.5% of the values lie above z, and 2.5% of the values lie

Step 4: Calculate P Value from Z Score. Finally, to calculate the P value from the Z score we have just determined, we are going to use the NORMSDIST function. Follow these steps to find the P value of each of the entries. First, insert a column for the P values. Then select cell E5.
