Amarine biologist is examining the effects of oil pollution on a population of seagulls (larus canus). he is particularly interested in determining whether oil pollution reduces the number of eggs that may be hatched in each seagull nest. during one breeding season, he has counted the number of eggs present in 16 seagull nests and recorded the distance from each nest to a nearby oil refinery. which step would best enhance the data from this study and allow the researcher to reach more confident conclusions?
