Question
the arm span and foot length were both measured (in centimeters) for each of 20 students in a biology class. the computer output displays the regression analysis.
predictor coef se coef t - ratio p
constant - 7.611 2.567 2.965 0.046
arm span 0.186 0.035 5.377 0.000
s = 1.61 r - sq = 63.0% r - sq(adj) = 64.9%
which of the following is the coefficient of determination?
0.63 0.79 0.65 0.81
El coeficiente de determinación, denotado como $R^2$, se muestra en la salida de la regresión como R-Sq. Este valor representa la proporción de la variabilidad de la variable dependiente que se explica por el modelo de regresión. En la salida dada, R-Sq es 63.0%, que se convierte a decimal como 0.63.
