Understanding Z-Scores - High School Math
Card 0 of 3
What is the 
-score for a value of 115 when the mean of the population is 103 and the standard deviation is 8?
What is the
A 
-score indicates whether a particular value is typical for a population or data set. The closer the 
-score is to 0, the closer the value is to the mean of the population and the more typical it is. The 
-score is calculated by subtracting the mean of a population from the particular value in question, then dividing the result by the population's standard deviation.

The 
-score indicates how close a particular value is to the population mean and whether the value is above or below the mean. A positive 
-score is always above the mean and a negative 
-score is always below it. Here, we know the value is below the mean because we have a negative 
-score.
