variables: women (late10’s~early 30’s) who are interested in make-up
② Geographical variables: the capital-centered region, dominant commercial market much floating population and online system (support exceptional places)
③ Socio-cultural variables: Consumption pattern (emotional consumption culture →rational consumption culture) from shrinking mind derived from the recession.
influenced by ‘Access to health care as % of total population’ and ‘Population per physician’.
We want to know the pure correlation effect between infant mortality rate and access to healthcare factor.
Method
-By analyzing data, find the correlation between 3 factors.
-Determine which one have strong influence on infant mortality rate, and try to exclude the other variable
for flu, or whatever. Having a little knowledge of statistics, the superintendent would know that it is unnecessary and inefficient to question each child: the proportion for the sample of as few as 100 children. Thus , the purpose of inferential statistics is to predict or estimate characteristics of a population from a knowledge of the characteristics of only a sample of the population.

Therefore, our team in the marketing research topics chooses the market of skin care vitamins, medicines that the market scale of 10 billion won based on 2010 fourth quarter. Among that market we choose the melasma treatment medicine field somewhat unfamiliar but recently showing a lot of attention in 30 to 40 woman, and we research the marketing strategies and techniques of melasma

2 and the variance is:
Standard Deviation
the square root of the variance
The probability that the observed relationship or a difference in a sample occurred by pure chance, and that in the population from which the sample was drawn, no such relationship or differences exist
Example, a p-value of .05
5% probability that the relation between the variables found in our sample is a "fluke."
같이 ‘노인’과 ‘복지’라는 용어에 대한 선호도가 노인복지 시설의 이용과 프로그램 참여를 결정하는 근간이 된다. 이러한 가설을 바탕으로 연구의 변수 개념과 조작적 정의를 살펴보겠다.
변수(변인, variable)란 연구하려고 하는 어떤 속성을 의미한다. 즉, 연구대상이 되고 있는----
(A).Isthere evidence that thesatisfaction rate is over 7.0?
(B).Isthere evidence that the satisfaction rate is over 7.0,if you know the population standard deviation is equal to 2?
