This table tests the null hypothesis that the variance of the error term is constant across the cells defined by the combination of factor levels. Since the significance value of the test, 0.718, is greater than 0.10, there is no reason to believe that the equal variances assumption is violated. Thus, the small differences in group standard deviations observed in the descriptive statistics table are due to random variation. The spread-versus-level plot is a scatterplot of the cell means and standard deviations from the descriptive statistics table. It provides a visual test of the equal variances assumption, with the added benefit of helping you to assess whether violations of the assumption are due to a relationship between the cell means and standard deviations. There is no apparent pattern in this plot, so there is no indication of such a relationship here.
