Correlation requires clearly identified explanatory and response variables.

True

False

Regression requires clearly identified explanatory and response variables.

True

False

Scatterplots require that both variables be quantitative.

True

False

Every LSRL will pass through the coordinate point (mean of x, mean of y).

True

False

Correlation changes as units of the variables change.

True

False

The LSRL minimizes the distances between the actual response variable values and the predicted values.

True

False

Switching the explanatory and response variables will NOT change the least-squares regression line.

True

False

The slope of the line is very senstive to outliers with large residuals.

True

False

The value of the coefficient of determination that is close to 1 does NOT guarantee that the relationship between the variables is linear.

True

False

The value of the coefficient determination close to 1 show that the explanatory variable is the cause of the response variable.
