Clear communication of procedures and findings is critical for scientific progress. One problem facing many research disciplines is the incorrect labelling in the literature of multivariable (i.e. many Xs) statistical models as multivariate (many Ys). Multivariate and multivariable statistical models are different statistical approaches and should be described as such. I assessed whether behavioural ecologists fall victim to the mislabelling plaguing other disciplines by reviewing relevant papers published in Behavioral Ecology between 2013-2023. My review shows that approximately 30% of multivariable models were incorrectly labelled as multivariate. Although this error rate is less severe than in other scientific disciplines it is nonetheless greater than zero.
