The term used to describe the extent of variation in a set of values is known as what?

The term used to describe the extent of variation in a set of values is known as dispersion. Dispersion refers to how spread out the values in a data set are in relation to the central value, which can help in understanding the variability within the data. It provides insight into how much the individual data points differ from the average or mean value.

Dispersion encompasses various statistical measures that quantify this variation, including range, variance, and standard deviation, but the term itself broadly captures the concept of variability. Understanding dispersion is crucial in assessment administration as it helps in analyzing property values and their distribution across a given area.

While standard deviation is a specific measure of dispersion that indicates the average distance of each data point from the mean, the broader term encompasses other aspects of variability as well. Therefore, referring to it as dispersion captures the overall idea of variation in a data set better than more specific measures or single value indicators.
