Question

Answer True or False to the statements below.

1) The coefficient of determination measures the variation in the dependent variable that is explained by the regression model

2) A student might expect that there is a positive correlation between the age of his or her computer and its resale value.

3) The variable that is being predicted in regression analysis is the independent variable.

4) If there is no correlation between the independent and dependent variables, then the value of the correlation coefficient must be –1.

Answer 1

1) The coefficient of determination measures the variation in the dependent variable that is explained by the "independent variable" not a regression model.

Therefore,

The answer is True.

2) As the age of computer increases, there resale value decreases.

Therefore,

The answer is False.

3) The variable that is being predicted in regression analysis is the "dependent variable"

not a independent variable.

Therefore,

The answer is False.

4) If there is no correlation between the independent and dependent variables, then the value of the correlation coefficient must be 0 (zero) not a -1.

Therefore,

The answer is False.
