Quizplus · Accepted Answer

The sum of squares for a distribution of scores is found by taking the sum of the squared differences between each score (X) and the mean (\bar{X}). This formula is represented as \sum ( X - \bar { X } ) ^ { 2 }.

The Sum of Squares for a Distribution of Scores Is ∑(X−Xˉ)2\sum ( X - \bar { X } ) ^ { 2 }∑(X−Xˉ)2

The Sum of Squares for a Distribution of Scores Is $\sum ( X - \bar { X } ) ^ { 2 }$
