Conclusion:
The information was not appropriate because we now have done a experiment through reality and a collection group of amounts may be prone to come up many times (possibility in idealism), but not usually (reality in optimism).
If a better result is being closer to the Punnett Potager value, then ways to improve results include having more people do that experiment and increasing the amount of probability simply by increasing the amount of individual M&M selection.
This lab was not at all hard, yet that produced a great and educational environment.
Conceivable errors contain wrong M&M selection, incorrect amount of tries of selection, calculation problems, incorrect readings, class data not really collected effectively because of group participation, and individual erroneous information, and false supply of data..
