**Sometimes we need a standardized scale to measure a value's distance from the center. **

**A Z-score indicates how many STANDARD DEVIATIONS a value is from the mean. **

**The official formula is:**

**So let's say the MEAN is 100 and the Standard Deviation is 15. **

**If you are given a value of 132, you just plug that into the formula above. **

**132 - 100 = 32**

**32 / 15 = 2.133 **

**VOILA - Your Z-Score is 2.133**
