range variance

**range variance**

Range variance refers to the measure of variability or dispersion within a specific data range. In statistics and data analysis, it helps quantify how spread out values are between the minimum and maximum points of a data set. Understanding range variance is essential for identifying trends, detecting outliers, and making informed decisions based on the consistency or volatility of data within a defined interval. This concept is commonly applied in fields such as finance, quality control, and scientific research.
