Definitions:

Pearson Correlation

A measure of the linear correlation between two variables, denoted by the correlation coefficient, ranging from -1 to 1, where 1 indicates a perfect positive linear relationship, -1 a perfect negative linear relationship, and 0 no linear relationship.

P-value

The probability of obtaining test results at least as extreme as the results observed, assuming that the null hypothesis is true.

Pearson Correlation

A measure of the linear correlation between two variables, giving a value between -1 and 1 where 1 implies a positive linear correlation, -1 a negative linear correlation, and 0 no linear correlation.

Null Hypothesis

A hypothesis that there is no significant difference or effect, serving as the default assumption to test against in statistical analysis.
