standard deviation
This term is a technical statistical measure used to quantify the spread of a data set. A low value indicates that the data points tend to be very close to the mean, while a high value suggests that the data points are spread out over a wider range of values.
In professional and academic contexts, it is frequently contrasted with variance, which is the square of the standard deviation. While variance provides a mathematical basis for further statistical analysis, standard deviation is preferred for reporting results because it is expressed in the same units as the original data, making it more intuitive for interpretation.
