A researcher studying the effects of a new fertilizer on crop yields plans to carry out an experiment in which different amounts of the fertilizer are applied to 100 different one-acre parcels of land. There will be four treatment levels. Treatment level 1 is no fertilizer, treatment level 2 is \(50 \%\) of the manufacturer's recommended amount of fertilizer, treatment level 3 is \(100 \%\), and treatment level 4 is \(150 \%\). The researcher plans to apply treatment level 1 to the first 25 parcels of land, treatment level 2 to the second 25 parcels, and so forth. Can you suggest a better way to assign treatment levels? Why is your proposal better than the researcher's method?
