Common Questions About Standard Deviation
Opportunities and Realistic Risks
Standard deviation measures the amount of variation or dispersion from the average value in a set of data. It's calculated by finding the square root of the average of the squared differences from the mean. This value helps us understand how spread out the data is and whether it's likely to fall within a certain range. A low standard deviation indicates that the data points are close to the mean, while a high standard deviation suggests that the data points are more spread out.
