Use the slider to see how the shape of the chi-square density function changes
as the degrees of freedom change as in Figure 7.9. Enter different values of chi-square in the
box (and hit the "return" key) to evaluate their probabiltiies and enter different
probabilities to find corresponding critical values.
Note: This applet only computes one-tailed probabilities as in Figure 7.10(a).
