실험설계에서의 타당도란 실험설계가 얼마나 짜임새 있게 잘 고안되어 있으며 그로 인해 가외변인들의 효과가 얼마나 배제될 수 있는가의 정도를 말한다. 여기에서 타당도는 검사라는 측정도구에 초점을 맞춘 것이 아니라 측정결과, 즉 자료에 그 초점을 맞추고 있다. 타당도란 한 검사 또
1. Introduction
1) Research purpose
To cope with quickly and flexible to 21st century global market conditions, changing rapidly,
Organizations and government organizations form and manage the various type of subgroups or teams away from the traditional organization Despite of drawbacks such as increasing in time and material costs also likelihood of conflict, the main purpose of focusing on
statistical relationships involving dependence. If correlation is close to positive 1, both statistics so related with each other.
1.1.3. Correlation between CSI of consumers' consumption and CSI of apparel consumption is very close to 1, in other words, they are very related with each other.
1.1.4. Correlation between CSI of expected income in future and CSI of apparel consumption is very clo
continuously. It's already over $ 21,000. New Zealand's GDP per capital is similar with Korea.

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.
