Der Korrelationskoeffizient r von Bravais-Pearson stellt selbst ein Mass für die Effektstärke dar. Um zu bestimmen, wie gross der gefundene Zusammenhang ist, kann man sich an der Einteilung von Cohen (1992) orientieren: r = .10 entspricht einem schwachen Effekt

Medan Pearson’s R är ett mått på sambandets riktning och styrka och går mellan -1 och +1, medan R2 går mellan 0 och 1 och är ett mått på hur mycket av variationen i den beroende variabeln som förklaras av den oberoende variabeln. Pearson’s correlation Introduction Often several quantitative variables are measured on each member of a sample. If we consider a pair of such variables, it is frequently of interest to establish if there is a relationship between the two; i.e. to see if they are correlated. Die Korrelation nach Bravais-Pearson berechnet den linearen Zusammenhang zweier intervallskalierter Variablen.
The form of the definition involves a "product moment", that is, the mean (the first moment about the origin) of the product of the mean-adjusted random variables; hence the modifier product-moment in the name. Below are the proposed guidelines for the Pearson coefficient correlation interpretation: Note that the strength of the association of the variables depends on what you measure and sample sizes.

Pearson's correlation coefficient is the covariance of the two variables divided by the product of their standard deviations. The form of the definition involves a "product moment", that is, the mean (the first moment about the origin) of the product of the mean-adjusted random variables; hence the modifier product-moment in the name.

Die Korrelation nach Bravais-Pearson berechnet den linearen Zusammenhang zweier intervallskalierter Variablen. Da stets der Zusammenhang zwischen zwei Variablen untersucht wird, wird von einem "bivariaten Zusammenhang" gesprochen.
The Pearson correlation generates a coefficient called the Pearson correlation coefficient, denoted as r. The Pearson Correlation Coefficient (which used to be called the Pearson Product-Moment Correlation Coefficient) was established by Karl Pearson in the early 1900s. It tells us how strongly things are related to each other, and what direction the relationship is in! The formula is: r = Σ (X-Mx) (Y-My) / (N-1)SxSy Want to simplify that? Pearson's r Correlation This widely-used coefficient measures the strength of a linear association between variables. Spearman's Rank Order Correlation The most common non-parametric measure, Spearman's is used when data are not normally distributed. A Pearson product-moment correlation coefficient attempts to establish a line of best fit through a dataset of two variables by essentially laying out the expected values and the resulting Pearson's correlation coefficient indicates how far away the actual dataset is from the expected values.

The calculation of the p-value relies on the assumption that each dataset is normally distributed. (See Kowalski for a discussion of the effects of non-normality of the input on the distribution of the correlation coefficient.) The Pearson correlation coefficient measures the linear relationship between two datasets. The calculation of the p-value relies on the assumption that each dataset is normally distributed. (See Kowalski for a discussion of the effects of non-normality of the input on the distribution of the correlation coefficient.) The Pearson product-moment correlation coefficient, often shortened to Pearson correlation or Pearson's correlation, is a measure of the strength and direction of association that exists between two continuous variables.
