WebThe 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. WebThe test of homogeneity is used to determine whether two or more independent samples differ in their distributions on a single variable of interest: comparing two or more groups on a categorical outcome.

Web38 CHAPTER 3. THE SCALING HYPOTHESIS The assumption of homogeneity is that, on going beyond the saddle-point approxi-mation, the singular form of the free energy (and of any other thermodynamic quantity) retains a homogeneous form f sing.(t,h)=t 2−αg f $ h t∆ % (3.3) where the actual exponents α and∆depend on the critical point being ... WebIn this chapter, you will learn the three major applications of the chi-square distribution: the goodness-of-fit test, which determines if data fit a particular distribution, such as in the lottery example. the test of independence, which determines if events are independent, such as in the movie example. the test of a single variance, which ... WebType of significance estimate: Asymptotic, exact, or Monte-Carlo estimate methods are used to test the significance of the McNemar, marginal homogeneity, sign, and Wilcoxon tests. SPSS interface: These methods are available in SPSS, which can be accessed by selecting “analysis,” then “nonparametric,” and then the two related samples. aig automotive standards
