## How to Standardize Data (Z-Score)
### Formula
**Z = (X - Mean) / SD**
Standardization (z-score transformation) converts data to have mean 0 and standard deviation 1. Each standardized value tells you how many standard deviations the original value is from the mean. This is the most common preprocessing step in statistics and machine learning.

हल किया गया उदाहरण
Dataset has mean 60 and SD 10. Standardize the value 75.
- Z = (75 - 60) / 10 = 15 / 10 = 1.5
- 75 is 1.5 standard deviations above the mean
- After standardization, the value is 1.5
