ANOVA de Welch: ANOVA de uma via para variâncias heterogêneas no SPSS

In this video, I explain how to perform Welch's ANOVA, a one-way ANOVA suitable for data with non-homogeneous variances. I explain how to do it in SPSS, how to interpret it, and how to report your results. The video also includes a discussion of the assumptions of one-way ANOVA, with emphasis on the assumption of normality. I also teach how to test the normality of the dependent variable separated by groups. ANOVA assumptions: 0:26 Normality test with distributed variable by groups and outlier check: 8:20 Levene's test: 11:09 Welch's ANOVA: 12:43 Database download: https://drive.google.com/file/d/1xLw-...
