Table 7. The scores of two principal components (extracted from 21 component variables).

	P1	P2	P3	P4	P5	P6	P7	P8	P9	P10	P11	P12	P13	P14	P15	P16	P17	P18	P19	P20	P21
Component 1 60.89%	0.04	−0.05	−0.07	0.08	−0.05	0.08	0.08	−0.05	0.05	0.08	0.08	−0.05	−0.07	−0.05	0.05	0.05	−0.05	0.05	0.06	−0.06	−0.05
Component 2 35.78%	0.10	0.09	−0.07	0.03	0.10	0.02	0.02	0.09	0.10	0.01	0.02	0.10	0.05	0.09	0.10	0.10	−0.10	0.10	−0.03	0.08	0.10

a) 60.89% and 35.78% stand for the percentage of variance contribution and two principal components contribute to 96.67% of the total variance.

b) The scores are used for the transformation between two principal components and 21 component variables.
