Morphology
The meaning is directly built from 'experimental' (related to experiments) modifying 'variable' (an element that can assume values), so a learner who knows both words can infer it refers to a variable used or manipulated in an experiment. This noun-modifier composition is a common, transparent pattern in English (and in many other languages), making the MWE immediately understandable at B1 level.
Etymology
Experimental variable comes from work in a lab: imagine a scientist changing one thing, the variable, during an experiment, the experimental part, to watch what happens. So it means 'a thing you change on purpose to see its effect'.
