What is the Formula for Standard Deviation?

Opportunities and Realistic Risks

Standard deviation is a measure of the amount of variation or dispersion from the average value. In simpler terms, it shows how spread out numbers are from the mean. A low standard deviation indicates that the numbers are closely packed around the mean, while a high standard deviation shows that the numbers are more spread out. Think of it like measuring the height of a class of students – if the standard deviation is low, most students are around the average height, while a high standard deviation means some students are significantly taller or shorter than the average.
