Correlation Coefficients > Intraclass Correlation. Intraclass Correlation. Intraclass correlation measures the reliability of ratings or measurements for clusters — data that has been collected as groups or sorted into groups. A related term is interclass correlation, which is usually another name for Pearson correlation (other statistics can be used, like Cohen’s kappa, but this is rare). Analysis of Variance (ANOVA) Intraclass Correlation Calculator. This calculator will compute the intraclass correlation for an analysis of variance (ANOVA) study, given the between-groups mean square, the within-groups mean square, and the number of subjects in each group. Please enter the necessary parameter values, and then click 'Calculate'.

Correlation coefficient. The correlation coefficient, r, ranges from -1 to +1. The nonparametric Spearman correlation coefficient, abbreviated rs, has the same range. This latter value is sometimes denoted by the Greek letter ρ (rho). The problem concerns calculating a correlation between two variables when it is not clear which variable should be X or Y for a given row of data. The simplest, and most common, solution is to use an intraclass correlation coefficient. There are a number of different intraclass correlations, and the classic reference is Shrout and Fleiss (1979). An intraclass correlation (ICC) can be a useful estimate of inter-rater reliability on quantitative data because it is highly flexible. A Pearson correlation can be a valid estimator of interrater reliability, but only when you have meaningful pairings between two and only two raters. What if you have more? Correlation coefficient is a measure of degree between two or more variables. This measurement of correlation is divided into positive correlation and negative correlation. Positive Correlation happens when one variable increases, then the other variable also increases.
