Question

ch 4 the correlation value, r, makes no distinction between the explanatory and response variable. true false

Explanation:

The correlation coefficient \( r \) measures the strength and direction of a linear relationship between two variables. It does not distinguish which variable is the explanatory (independent) and which is the response (dependent). For example, if we calculate \( r \) for variables \( x \) and \( y \), swapping \( x \) and \( y \) gives the same \( r \) value.

Answer:

True
