The formula to calculate the sum of squares (Σx²) is:
\[ \Sigma x^2 = \sum (x^2) \]
Where:
Σx², in statistical notation, represents the sum of the squares of a set of values (x). This is often used in various statistical formulas and calculations, such as calculating the variance or standard deviation in a data set. It involves squaring each individual value in the set, and then summing all these squared values together.
Let's assume the following values:
Using the formula to calculate the sum of squares (Σx²):
\[ \Sigma x^2 = 2^2 + 3^2 + 4^2 = 4 + 9 + 16 = 29 \]
The Sum of Squares (Σx²) is 29.
