The results obtained by survey on 599 respondents of different age groups for preference of 84 prepared foods were subjected to statistical principal component analysis, factor analysis, analysis of variance, scheffe verification, and discriminant analysis so as to find a structure of preference for foods.
The results may be summarized as follows:
1. The results of the factor analysis indicate that 84 prepared food items may be classified into 3 groups and that by knowing an indvidual´s preference to one prepared food, one can presume his preference to the others in the same group without carrying out actual test.
2. The results from an analysis of variance showed that most of primary school children extremely liked snacks, seniors liked Korean cooking, primary school children and collegians had weaknesses for western cookings while kindergarden children and adults over 50 years old disliked them.
