### Conduct and Interpret a Canonical Correlation

What is Canonical Correlation analysis? The Canonical Correlation is a multivariate analysis of correlation. Canonical is the statistical term for analyzing latent variables (which are not directly observed) that represent multiple variables (which are directly observed). The term can also be found in canonical regression analysis and in multivariate discriminant analysis. Canonical Correlation analysis is

### Conduct and Interpret a Point-Biserial Correlation

What is Point-Biserial Correlation? Like all correlation analyses the Point-Biserial Correlation measures the strength of association or co-occurrence between two variables. Correlation analyses express this strength of association in a single value, the correlation coefficient. The Point-Biserial Correlation Coefficient is a correlation measure of the strength of association between a continuous-level variable (ratio or interval

### Measures of Association

The measures of association refer to a wide variety of coefficients that measure the statistical strength of the relationship on the variables of interest; these measures of strength, or association, can be described in several ways, depending on the analysis. There are certain statistical distinctions that a researcher should know in order to better understand

### Correlation Ratio

Correlation ratio is a coefficient of non-linear association. In the case of linear relationships, the correlation ratio that is denoted by eta becomes the correlation coefficient. In the case of non-linear relationships, the value of the correlation ratio is greater, and therefore the difference between the correlation ratio and the correlation coefficient refers to the
