I. Introduction
In 1983, Nongshim-Kellogg launched the first cereal in Korea. A year later, Dongsuh-food corporation also released a cereal for breakfast. Since then, cereal market in Korea grew up every year. The number of product lines of cereal being sold in current Korean market is over 30. So people can now choose a product according to their own preference. Consumers have several purpose
Mean
sum of all the scores divided by the number of scores
The mean is a good measure of central tendency for roughly symmetric distributions
It can be misleading in skewed distributions since it can be greatly influenced by extreme scores.
Variance
The variance is a measure of how spread out a distribution is.
It is computed as the average squared deviation of each number from its mean.
Ⅰ. Introduction
The goal of Multivariate statistical analysis(MSA) is dimension reduction of data. Especially, visualization of data is very important. In various methods of MSA, Multidimensional scaling(MDS) is introduced and discussed as a graphical method to complement conventional descriptive and confirmatory methods in validation and analysis of QOL data. The use of MDS is illustrated i
did multivariate analysis by using discriminant analysis.
The aim of this study is to verify whether the government chose poor performance universities in a reasonable way or not. We will do that by doing discriminant analysis and comparing the results against those of the government’s list. In that way, we would like to explore the data and investigate validity of the government’s list.
