STEP-DOWN ANALYSIS AND SIMULTANEOUS CONFIDENCE INTERVALS IN MANOVA
Abstract:
Two fundamental ways of analyzing a multivariate analysis of variance (MANOVA) problem in more detail are the stepdown analysis (Roy, 1958; Bock, 1963), and the use of simultaneous confidence intervals (Gabriel, 1968; Morrison, 1967). Assuming a global test of significance, such as Wilk's A, has indicated non- ohance association between the independent variable and the set of dependent variables (this paper will limit discussion to the one- way design), the aforementioned methods may be used to deter- mine which of the dependent variables and/or groups are responsible for the global significance.

Interpretation of Confidence Intervals
Confidence intervals have confidence coefficients that are crucial for their interpretation. The most common confidence coefficients are 0.90, 0.95, and 0.99, which can be written as percentages–90%, 95%, and 99%, respectively.
Suppose a person calculates a confidence interval with a confidence coefficient of 0.95. In that case, they can...
