A one-way analysis of variance was conducted to evaluate the null hypothesis that there is no difference high school students' level of satisfaction with school based on their family's socioeconomic status. The independent variable, socioeconomic status, included three groups: Low (M = 21.36, SD = 4.75, n = 147), Moderate (M = 24.10, SD= 4.15, n = 153), and High (M = 29.73, SD = 6.85, n = 135). The researcher found, F(2 ,? ) = 4.64, p = .01. What is the df for the denominator?
F(2 , 435)
F(2 , 432)
F(2 , 438)
