Correlation tests. When the null assumption is ρ 0 = 0, independent variables, and X and Y have bivariate normal distribution or the sample size is large, then you may use the t-test. When ρ 0 ≠ 0, the sample distribution will not be symmetrical, hence you can't use the t distribution. In this case, you should use the Fisher transformation to transform the distribution.

The Sample Correlation Coefficient (R) is a statistical measure used to determine the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative correlation, 1 indicates a perfect positive correlation, and 0 indicates no correlation. Historical Background

A correlation of -1.0 shows a perfect negative correlation, while a correlation of 1.0 shows a perfect positive correlation. A correlation of 0.0 shows no linear relationship between the movement of the two variables. How to Calculate Sample Correlation Coefficient R?
