WebFeb 22, 2024 · Linear regression is used to find a line that best “fits” a dataset.. We often use three different sum of squares values to measure how well the regression line actually fits the data:. 1. Sum of Squares Total (SST) – The sum of squared differences between individual data points (y i) and the mean of the response variable (y). SST = Σ(y i – y) 2; 2. … WebNov 23, 2024 · Steps to calculate the coefficient of determination Step 1: Firstly find the correlation coefficient (or maybe it is mentioned in the question for e.g, r = 0.467). R = n (∑xy) – (∑x) (∑y) / √ [n∑x 2 – (∑x) 2 ] [n∑y 2 – (∑y) 2] Step 2: Now square the correlation coefficient 0.657 2 =.432
