Red hair hazel eye babies: 6 Conclusion: The data was not accurate because we have done a experiment through reality and a set group of numbers may be likely to come up a number of times (possibility in idealism), but not always (reality in optimism). If a better result is being closer to the Punnett Squares value, then ways to improve results include having more people do this experiment and increasing the number of probability by increasing the number of individual M selection. This lab was relatively simple, yet it produced a fun and educational environment. Possible errors consist of wrong M selection, wrong amount of tries of selection, calculation problems, wrong readings, class data not collected properly because of group participation, and individual inaccurate information, and false supply of data. .
