Given that relatively little is known about the development of resilience in early childhood, this longitudinal study aimed to identify preschool resource factors associated with young children’s mental health resilience to family adversity. If the statistical assumptions of a MANCOVA can be met, it is a much more powerful inferential statistic that can yield both main and interactional effects while controlling for a covariate. A factorial MANOVA may be used to determine whether or not two or more categorical grouping variables (and their interactions) significantly affect optimally weighted linear combinations of two or more normally distributed outcome variables. Mengapa hampir sama dengan uji manova? sebab memiliki kesamaan, yaitu ada lebih dari satu variabel dependen yang diuji. On consulting with my supervisor I got to know that over 89% of research candidates face the same problem and seek for guidance and help.
