Psychology definition for Correlation Coefficient in normal everyday language, edited by psychologists, professors and leading students. Help us get better.
The Pearson correlation, also referred to as the Galton-Pearson correction (Blyth, 1994), is arguably the most utilized correlation coefficient, and there is some research to support this. For example, a review of more than 18,000 psychology articles published in 2014 found that an effect size...
In this case the coefficient is -0.541 meaning that there exists a moderate inverse association between X and Y. The higher the number of cigarettes, the lower the longevity - a dose-dependent relationship. The resulting p-value of 0.0022 shows that observing such a negative correlation would ...

The correlation, or co-relation, coefficient is typically attributed to Karl Pearson who developed the formalized idea of correlation during the mid- to late 1800s. However, the beginning of the idea of correlation may have come from Sir Francis Galton, cousin of Charles Darwin. Galton worked ...

Data Extraction Firstly, Pearson's correlation coefficient (r) was used as a measure of effect size. Noteworthy, the correlation coef- ficients were extracted from survey studies that did not include treatment and from mindfulness-based intervention studies that examined bivariate correlations among ...
