- 1
Standard deviation measures the spread or variation in a data set, often visualized as a bell-shaped curve called a normal distribution.
- 2
Approximately 68% of data points fall within one standard deviation from the mean, while 95% fall within two standard deviations.
- 3
The formula for standard deviation involves calculating the square root of the variance, which is the average of the squared differences from the mean.
