IB Biology Practical Investigations/Satistics/Mythbusting: Girls can buoyt catch demonstration The results of the investigation proven that our hypothesis was correct. That is, boys do catch bankrupt than young ladys. This can be observed by examining our data. The nasty number of catches for the boy backstop was 4.6 taboo of a feasible 5.

Because only one boy and one girl were used to test the hypotheses, the results s tag the catching ability of only one person ! from distributively sex. This leaves too much uncertainty as the goal is to bring up out out which population, boys or girls are better catchers. 5.Slippery ball. The sweat, moisture, and annoyed grass made the ball increasingly slippery as the lab went on. The above weaknesses and limitations could be improved in the pursuit ways: 1.The distance could be kept the same by measuring off a certain distance fountain to...If you want to get a full essay, order it on our website: OrderCustomPaper.com
