Multivariate analyses are power-hungry. In a simple t-test, a sample of 30 might suffice. In multivariate analysis—such as Structural Equation Modeling (SEM) or Multivariate Analysis of Variance (MANOVA)—the requirements are much steeper. A robust design must account for the number of variables relative to the sample size. The "rule of 10" (10 participants per variable) is often cited as a heuristic, though complex models may require significantly more.

In modern research interpretation, the focus has shifted away from simple p-values toward effect sizes. A p-value tells you if an effect exists; an effect size tells you how strong it is.
