Analysing with One-way Layout Method

Use the one-way layout method to verify whether there is a relation to the results achieved based on one condition. Analysis of variance is carried out with this method.

Calculation

	Sum of squares (S)	Degree of freedom (θ )	Variance (V)	Variance ratio (F)	[A] = Σ i (Σ j Xij)2 ⎟	N
					[AS] = Σ i Σ j (Xij)2
Factor	SA = [A] - [X]	θ A = A - 1	VA = SA ⎟ θ A	FA = VA ⎟ VE
