Psychology definition for Correlation Coefficient in normal everyday language, edited by psychologists, professors and leading students. Help us get better.
Within psychology, or any other social science discipline, a correlation is calculated when one is looking to study variables and determine a possible relationship or association between them. Answer and Explanation: Specifically, the correlation coefficient (r) is the statistical measure of a potential...
Interpretation of the Coefficient of Correlation: Merely computation of correlation does not have any significance until and unless we determine how large must the coefficient be in order to be significant, and what does correlation tell us about the data? What do we mean by the obtained val...

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 ...
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...
(2007). Testing a correlation coefficient's signifi- cance: Using H0: 0 < ρ≤λ is preferable to H0: ρ = 0. Psychology Science, 49, 74-87.Testing a correlation coefficient's significance: Using H0: 0 < ρ < λ is preferable to H0: ρ = 0 - Kubinger, Rasch, et al. - 2007...
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 ...
Spearman’s Coefficient Spearman's Rank Correlation Coefficient (ρ or rs) measures the strength and direction of the monotonic relationship between two ranked variables. It assumes that the data can be ranked and that the relationship between the variables is monotonic, meaning it consistently ...
As PC2 had a high coefficient for oral reading time, participants with a higher tracking speed limit tended to read faster orally (see Supplementary Fig. 3 for a scatter plot between the tracking speed limit and oral reading time). Fig. 5 Individual PC2 scores are plotted as a function of...
