Summary of Correlation
A correlation coefficient describes the degree of correlation between two variables and ranges from negative one, or a perfect negative correlation, to positive one, or a perfect positive correlation. In order to visualize data points, a correlation is graphed in a scattergram. If the coefficient is used on interval or ratio data, it is called a Pearson product moment correlation and must be used on linear relationships. The larger the sample size, the more closely that the correlation coefficient represents the true population.
