Quizplus · Accepted Answer

To find the sum of squares for $x$, $\sum ( x - \bar { x } ) ^ { 2 }$, first calculate the mean of $x$ values: $\bar{x} = \frac{5 + 9 + 10 + 7 + 7 + 10 + 6 + 8}{8} = \frac{62}{8} = 7.75$. Then, calculate each $x - \bar{x}$ squared and sum them: $(5 - 7.75)^2 + (9 - 7.75)^2 + (10 - 7.75)^2 + (7 - 7.75)^2 + (7 - 7.75)^2 + (10 - 7.75)^2 + (6 - 7.75)^2 + (8 - 7.75)^2 = 23.5$.
