Quizplus · Accepted Answer

The degree of freedom for testing the significance of each independent variable's coefficient in a multiple regression analysis is calculated as n - p - 1, where n is the number of observations and p is the number of independent variables. Therefore, the degree of freedom in this analysis is 697 - 17 - 1 = 679.
