While I myself did not take measurements of rats, the first four colums are data I have received from a student in Mr. Kirste's science class. The other three columns are ratios of the measurements that I was given, and I have found some interesting patterns. In the mass/tail ratio, not counting the fluctuation between days 9 and 13, the ratio increased according to a semi-complex pattern: The pattern started at 14, and then the number of increase went down two in the ones, and up one in the tens. Because of that, 14 was added, then 22, then the fluctation, then 30. Another way of saying this is that, besides from Day 9-13, the increase amout went up by eight. On the tai/head ratio, again not counting 9-13, the numbers stayed centered around one half. On the mass/head ratio, 6 and 13 round to about the same, and the ratio of the difference between them is equal to them. Also on the mass/head ratio, after a longer period of time, the head almost surpasses the mass, and probably will in the future. As for averages, the tail average increase was 3.11 mm, the mass average increase was 1.41 grams, and the head circumference average increase was 2.18.
