MANOVA requires: a.) The dependent variables to be heteroscedastic. b.) More than one outcome variable. c.) Sphericity. d.) A stricter significance level than ANOVA.
What makes ANCOVA different from ANOVA? a. ANCOVA can include dummy variables. b. ANCOVA can include one or more continuous variables that predict the outcome. c. ANCOVA can include continuous variables that are not part of the main experimental manipulation but influence the dependent variable. d. ANCOVA can include continuous variables that are not part of the main experimental manipulation but influence the independent variable.

When you have only one independent variable. c. When you have two or more independent variables. d. Never for repeated-measures ANOVA.
We already know that when the homogeneity of variances assumption is violated in Independent-Samples t-Test you rely on the Levene's Test. What is the test (or ratio) that we fall on when the homogeneity of variances assumption is violated in ANOVA? In addition to theoretical understanding, through your explanation of this topic you should show an understanding of the practical use of it in SPSS as well.
A t-test should be used when: Select one: a. The population variance is known b. the population variance is unknown c. the sample size is small d. (a) and (c)
residuals (error terms) is violated, the Durbin-Watson statstic is used to test to determine if there is signticant among the residuals When the assumption of normality, probability independent, probability independent, autocorelabion normalty, autocorelation O O
