The third section consists of the floatation of refined scale with lesser sample size as liken to prior floatation of scale to check the inter-item correlation amongst items so that get more refined scale. The fourth section consists of the floatation of refined scale with lesser sample size as liken to prior floatation of scale to check the reliability (if-item deleted) of factors, association among factors, and cause and effect relationship amongst factors.
