How do you find the ss in statistics

WebMay 26, 2024 · In statistics, the formula for this total sum of squares is Σ (x i - x̄) 2 Here the symbol x̄ refers to the sample mean, and the symbol Σ tells us to add up the squared differences (x i - x̄) for all i . While this formula works for calculations, there is an equivalent, shortcut formula that does not require us to first calculate the sample mean. WebStep 1: Find the mean. \bar {x}=\dfrac {2+2+5+7} {4}=\dfrac {16} {4}=4 xˉ = 42 + 2 + 5 + 7 = 416 = 4 The sample mean is 4 4 pencils. Step 2: Subtract the mean from each score. Step 3: Square each deviation. Step 4: Add the squared deviations. 4+4+1+9=18 4 + 4 + 1 + 9 = 18 Step 5: Divide the sum by one less than the number of data points.
