Abstract
A survey of 1600 young womens in the Western Japan was made to investigate the degree of consumrs'requirement of 55 questionaire items on five kinds of women's garments for the summer. The data have been analyzed and following results were obtained:
(1) The CV% is suitable to express the variation of the degree of consumers' end-use requrement. The lower CV% means that the degree of requirements coincide well among pollees, showing that the result is highly reliable.
(2) The CV% is affected by the shape of a frequency histogram of the degree of end-use requirement. When the CV% is more than 40%, two peaks appear in a histogram, suggesting that the degree of the requirement is abnormal.
(3) The significantly high negative correlation has been noticed between the degree of end-use requirement and the value of CV%. The greater the degree of requirement, the less the value of CV%.
It means that the consumer's requirement coincide well among pollees.
(4) The averages of CV% ofthe aesthetic appeal, specific function and comfort of T-shirt and summer sweater are more than 30%.
