This simple online X-Xbar 2 calculator helps you find the sum of squared deviation for the given set of numbers. If xi 0 then n i 1xi2 n i 1 n j 1xixj n i 1x2i n i 1 n j 1 j ixixj n i 1x2i On the other hand by the Cauchy-Schwarz inequality n i 1xi2 n i 11 xi2 n n i 1x2i So if n is fixed the sum of squares and the square of the sum. X Mxy1 y 16 Sum of Squares S. In a set of measure SS is calculated as below. To describe how well a model represents the data being modelled the sum of squares formula is used. Sum of squares SS is a statistical tool that is used to identify the dispersion of data as well as how well the data can fit the model in regression analysis Regression Analysis Regression analysis is a set of statistical methods used to estimate relationships between a dependent variable and one or more independent variables.
Column B below is the gap between x in Column A and the average of Column A.
