Answer: 1450
The total sum of squares (TSS) is calculated by adding the explained sum of squares and the residual sum of squares. From the table: - Explained sum of squares = 825 - Residual sum of squares = 625 TSS = Explained SS + Residual SS = 825 + 625 = 1450 This is a fundamental concept in regression analysis where the total variation in the dependent variable is partitioned into explained variation (by the model) and unexplained variation (residual).
