SOS (Sum of Squares)

Sum of Squares (SOS) is a statistical method used to measure how much differences or deviations exist within a set of data. It involves adding up the squared differences between each data point and a target value, such as the average. This sum helps quantify the overall variability or spread in the data. In simpler terms, SOS provides a way to assess how consistent or scattered the data points are, which is useful for making comparisons and understanding patterns in various fields like economics, engineering, and science.
