What Is an Acceptable Standard Deviation?

Statisticians have determined that values no greater than plus or minus 2 sd represent measurements that are are closer to the true value than those that fall in the area greater than ± 2sd.

What Is an Acceptable Standard Deviation?

An acceptable standard deviation is a measure of how much variation from the mean is considered tolerable. It is used in statistics to determine how well a set of data conforms to a specific value, such as the mean.

The standard deviation is also used to measure the variability of a population. The larger the standard deviation, the greater the variability.

A small standard deviation indicates that the data are close to the mean, while a large standard deviation indicates that the data are more spread out.
