The Transitivity Misconception of Pearson’s Correlation Coefficient

Abstract: Despite the relevance of correlational studies for most research domains, many students, teachers, and researchers alike hold misconceptions concerning the Pearson product-moment correlation coefficient. One of these, the transitivity misconception, has not yet been documented in a systematic way. This paper summarizes the first empirical study, using 279 university students, and examines the relationship between student-based and task-based factors and the appearance of this misconception. In particular, two … Show more

“…Here the complex relations refers to the non-bivariate normal data and non-linear and non-monotonic relations. Generally, the correlation value greater than 0.8 is described as strong correlation while the value less than 0.5 is described as weak correlation [ 34 ]. To measure the proportion of complex relationships in the microarray and RNA-seq datasets, we selected pairs of genes with distance correlation coefficients greater than 0.5 from the four datasets.…”

“…Therefore, if the distance correlation coefficient between two random variables is greater than the Pearson correlation coefficient then a complex relationship exists between them - non-binary normal data and non-linear nonmonotonic relationship. In general, correlation values greater than 0.8 are described as strong correlation, while values less than 0.5 are described as weak correlation ( Castro Sotos et al, 2009 ). To measure the proportion of complex relationships in the dataset, we selected gene pairs with distance correlation coefficients greater than 0.5 from eight datasets.…”

“…Eleven CAD candidate genes in the quiescent condition and 12 CAD candidate genes in the proliferative condition were moderate to highly correlated with AMT (Pearson r values between |0.5 and 0.75|). 45,46 AMT gene expression has previously been shown to be associated with CAD risk. 47 AMT was also differentially expressed between quiescent and proliferative conditions, suggesting that gene expression levels of CAD genome-wide association studies genes functioning in nitrogen metabolic enriched modules were reprogrammed due to changes in AMT expression levels, or vice versa.…”
