Coefficient of alienation from correlation coefficient

Pearson’s correlation coefficient returns a value between -1 and 1. The interpretation of the correlation coefficient is as under: If the correlation coefficient is -1, it indicates a strong negative relationship. It implies a perfect negative relationship between the variables. If the correlation coefficient is 0, it indicates no relationship.

Hence, a coefficient of determination of 0.64 or 64% means that the coefficient of correlation was 0.8 or 80%. (The range for the coefficient of correlation is -1 to +1, and therefore the range for the coefficient of determination is 0 to +1.)

Coefficient of Correlation is denoted by a Greek symbol rho, it looks like letter r. To calculate Coefficient of Correlation, divide Covariance by Standard Deviation of two variables (Sx, Sy). Coefficient of Correlation ranges between -1 and 1. r = -1 : Perfect Negative Correlation. r = 0 : No Correlation. r = 1 : Perfect Positive Correlation

The correlation is not 1, yet the observations lie on a smooth curve. The correlation coefficient is 0.70 rather than 0 because here the curve is not symmetric. Higher values of Y tend to go with higher values of X. A correlation coefficient is an inappropriate numerical summary of this data.

The association between two variables is often of interest in data analysis and methodological research. Pearson's, Spearman's and Kendall's correlation coefficients are the most commonly used measures of monotone association, with the latter two usually suggested for non-normally distributed data.

May 11, 2014 · The Spearman correlation is a nonparametric measure of the monotonicity of the relationship between two datasets. Unlike the Pearson correlation, the Spearman correlation does not assume that both datasets are normally distributed. Like other correlation coefficients, this one varies between -1 and +1 with 0 implying no correlation.
