Here is a way that works for me:
Mean - This is always the average so, mean could be like ‘what do you mean’ and in a sense is like a summary?
Median - Always the middle, think like medial? It’s a sort of mesh between the words.
Mode - The one that appears the most so, common mode or most - same amount of letters.
Range - Well, how far/long is the range. Think of a range for, well, anything!
Hope this helps at all!
