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
Analysis of variance chart of one-way layout method					[X] = (Σ Σ Xij)2 ⎟ AN
	Sum of squares (S)	Degree of freedom (θ)	Variance (V)	Variance ratio (F)	[A] = Σi (Σj Xij)2 ⎟ N
					[AS] = Σi Σj (Xij)2
Factor	SA = [A] - [X]	θA = A - 1	VA = SA ⎟ θA	FA = VA ⎟ VE	A : number of levels
Error	SE = [AS] - [A]	θE = A (N- 1)	VE = SE ⎟ θE
