Two correlation coefficients are in common use: Spearman rank-order correlation coefficient for nonparametric data and Pearson product-moment correlation coefficient for parametric data.
A Pearson product-moment correlation coefficient was computed to assess the relationship between the mean scores of the NSCES and the CES.
Whereas Pearson's product-moment correlation coefficient (Pearson's correlation) is a measure of the strength and direction of association that exists between two variables, it was used to define the relation between our two variables (leadership styles and strategy implementation).
The correlations between measured variables and jump height were tested between the swimming and volleyball groups using Pearson's product-moment correlation coefficient.

Pearson product-moment correlation coefficient was used to identify the correlation of variables studied.
Pearson product-moment correlation coefficient is widely used in determination of linearity between two variables.
Pearson's product-moment correlation coefficient, denoted by r, has been used in this study as a measure of the correlation between two variables x and y giving a value between +1 and -1 inclusive.
The Pearson product-moment correlation coefficient, a measure of the linear dependence between two variables, was measured between the CMLT and TSLT and showed a positive significant medium correlation ([r.sup.2] = 0.32; P = 0.0012) (Figure 4).
This correlation coefficient is named as "Pearson product-moment correlation coefficient," which is usually abbreviated to Pearson's r.
