Why is there a standard deviation?
- The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean.
- A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
- The more the data is distributed, the greater will be the standard deviation of that data.
- The standard deviation is used in finance by business owners to understand risk management and make better business decisions. It helps in calculating the margins of error that occur in the survey reports.
