WebTo estimate the degree to which any two measures are related to each other we typically use the correlation coefficient. That is, we look at the patterns of intercorrelations among our measures. Correlations between theoretically similar measures should be “high” while correlations between theoretically dissimilar measures should be “low”. WebCorrelation analysis determines whether two measurement variables are related and quantifies the relationship’s degree. At the same time, regression seeks to represent the relationship as an equation. For example, in the case of patients who attend an emergency department (ED), we could utilise correlation and regression.
