Morphology
The meaning is directly compositional: 'variance' (a difference/deviation) combined with 'analysis' (systematic examination) yields 'an examination of differences', which matches the MWE definition. This noun+noun combination follows a common, cross-linguistic pattern, so a B1 learner who knows both constituent meanings can reasonably infer the MWE meaning.
Etymology
Variance analysis comes from the simple picture of putting a 'budgeted' column next to an 'actual' column, finding the variance (the difference) and then doing an analysis (a careful look) to see why the numbers changed. So, it means checking those differences to understand the cause.
