About Standard Deviation
Standard deviation is a measure of the amount of variation or dispersion in a data set. It indicates how spread out the values are from the mean.
Interpretation:
- • Low SD: Data points are close to the mean
- • High SD: Data points are spread out from the mean
- • SD = 0: All values are identical
Uses:
- • Quality control
- • Financial analysis
- • Scientific research
- • Performance evaluation
