Multivariate analysis is the simultaneous comparison of three or more variables in order to determine the significance of their likenesses and differences. The technique has been in use for some thirteen years, but no simple account of the method has hitherto been available. An illustrative example from invertebrate paleontology is here used, but the method is applicable to any problem in geology involving several quantitatively known variables.
