multiple - choice question
what does the correlation coefficient measure?
how weak the relationship is between variables.
how strong the relationship is between variables.
rewatch

Explanation:

The correlation coefficient, such as Pearson's \( r \), ranges from \( - 1 \) to \( 1 \). A value close to \( 1 \) or \( - 1 \) indicates a strong linear relationship (positive or negative), while a value close to \( 0 \) indicates a weak linear relationship. So it measures the strength (and direction) of the relationship between variables.

Answer:

How strong the relationship is between variables.
