Question

Statistical Analysis The correlation coefficient is the statistical measure that primarily quantifies the strength and direction of a linear relationship between two variables. It provides a numerical value that ranges from -1 to 1, indicating the strength and nature of the relationship: positive correlation (values move in the same direction), negative correlation (values move in opposite directions), or no correlation (values don't exhibit a consistent pattern). Which of the following statistical tools primarily notices trends between two variables? pythagorean theorem t-test correlation coefficient

Answer 1

The statistical tool that primarily notices trends between two variables is the **correlation coefficient**. It quantifies the strength and direction of a linear relationship between the two variables, as you described.

The Pythagorean theorem is a mathematical principle related to right triangles, and the t-test is a statistical test used to compare means between groups, but neither of these directly measures the relationship between two variables in the same way the correlation coefficient does.
