Bahut hi aache se describe kiya he mem thanks
To find SD:
1. Take a series of observations.
2. Find their Mean.
3. Find the Deviation of Observations from Mean.
4. Square the Deviations.
5. Find the Mean of the Squared Deviations. This is called Variance.
6. Square root of Variance is Standard Deviation.
