Morphology
The meaning 'a statistical numeric indicator' is directly derivable from combining 'index' (an indicator or measure) with 'number' (a numeric value); the phrase simply names a numeric indicator and follows a straightforward noun–noun composition. This construction and concept are cross-linguistically common in statistics and therefore should be understandable to a B1 learner who knows both constituent words.
Etymology
The term index number comes from the words index (a pointer or list) and number. Imagine a finger pointing to one number on a chart that shows how prices go up or down. That's why an index number is a single number you use to 'compare' and see 'changes' over time or between places.
