Reason: to compare boiling point versus molecular weight you need reliable mean estimates (and precisions) for each substance. Splitting the 50 measurements evenly (10 each) gives balanced, unbiased estimates and reduces random error via averaging. Using the highest value or only one measurement would be biased or too imprecise.
