Morphology

analysis + of + variance

The phrase literally combines 'analysis' (systematic examination) and 'variance' (differences from the mean), so a learner who knows the constituents can infer it involves examining variance. However, the established technical meaning (the statistical procedure for comparing group means) is domain-specific and not fully predictable from general vocabulary knowledge, so it is only partially transparent.

Etymology

Analysis of variance comes from the idea of breaking the total variance, the 'differences' you see in a set of numbers, into parts and using analysis to look at each part. So the name shows the method's aim: to see if different 'groups' really cause the 'differences' you observe.
