Equamax rotation is described as which of the following?

• A. It is a standard rotation recommended
• B. It is a hybrid rotation of quartimax and varimax and is usually avoided due to erratic behavior
• C. It is used to rotate only a single factor
• D. It is a method for standardizing residuals

Answer: (B)

Equamax rotation is an orthogonal rotation that merges the aims of varimax and quartimax. It tries to simplify both the factor loadings (like varimax) and the variable loadings across factors (like quartimax) by balancing the weighting between the two approaches. In practice, this compromise can lead to unstable, sample-dependent results and less clear interpretability, so many analysts avoid it. That combination—being a hybrid of quartimax and varimax and often avoided due to erratic behavior—best fits the description. The other statements don’t capture what equamax does: it’s not a standard recommended rotation, not used to rotate only a single factor, and not a method for standardizing residuals.
