A new computational approach test for one-way ANOVA under heteroscedasticity

This paper proposes a new test statistic based on the computational approach test (CAT) for one-way analysis of variance (ANOVA) under heteroscedasticity. The proposed test was compared with other popular tests according to type I error and power of tests under different combinations of variances, means, number of groups and sample sizes. As a result, it was observed that the proposed test yields better results than other tests in many cases.     

Marital Satisfaction in Turkish Remarried Families: Marital Status,Stepchildren, and Contributing Factors

This study aimed to compare marital satisfaction among those of different marital status (first-married, postdivorce remarried, and postbereavement remarried) based on gender; to investigate the effect of decision of divorce on marital satisfaction of postdivorce remarried individuals; to examine the effect of type of death on marital satisfaction of postbereavement remarried individuals; and to examine the effect of stepchildren on marital satisfaction of remarried individuals. It was also intended to investigate the predictive power of demographic and contextual variables on marital satisfaction in different households. The Dyadic Adjustment Scale and an information form were administered to 116 first-married and 223 remarried individuals. To test the hypotheses of the study, analysis of variance, analysis of covariance, and stepwise multiple regression analysis were performed. Results revealed that there was no significant marital satisfaction difference in terms of marital status. Remarried individuals with residential stepchildren had lower marital satisfaction than those with nonresidential stepchildren and those without stepchildren. For first-married individuals, length of marriage and income predicted marital satisfaction. For postdivorce remarried individuals, gender and presence of mutual children were predictors. For postbereavement remarried individuals, length of current marriage and income were significant predictors. For those with stepchildren, only residence of stepchildren significantly predicted marital satisfaction. The findings of the study were discussed in the light of relevant literature.
