Global Soloist Rank: #1970
Global Soloist Score: 0
The standard score, or the Z-score in excel, is a way to calculate the difference between the actual score and the mean in standard deviation units. It also allows us to compare two examples from different populations. The z-value can be negative or positive. A negative z-score means that the value is less than the arithmetic value, and a positive z-score means that our value is greater than the arithmetic value. The Z-Score is calculated by subtracting the mean value of the data set from the data set to be calculated and dividing it by the standard deviation of the data set.
