Learn what constitutes a good standard deviation level and why lower values often indicate more consistent data, especially in finance and statistics.

10 views

A good level of standard deviation typically depends on the context, but in many fields, a lower standard deviation is preferred as it indicates data points are closer to the mean. For example, in finance, a standard deviation of less than 1% is often considered ideal for stable investments, whereas higher levels may signify more risk and variability.
