Section I: Theory
There was no specific theory tested in this lab, however the anticipate results of the various penny bedights should have been a convex curve.
Section II: Procedure
In the first experiment, 8 pennies were establish into a cup and dumped out. The number of heads in separately dump were counted and recorded in the data sheet. This was done 60 times. The similar experiment was repeated a second time; however, in this case 32 pennies were used for individually dump.
Section tether: Results
For the first experiment, the results showed a bell-shaped curve, with the bulk of the results of the 60 cast aside ranging between 3-5 heads per trial. For the second experiment, the number of heads was broken into range groups. The majority of the time, the results fell into the 11-14, 15-18, and 19-22 categories, with the middle category having by far the nearly occurrences.
Section IV: Conclusions
Whether 8 pennies or 32 pennies were used, the anticipate # of heads in each trial was 50%. When calculating each experiment using one of the three averaging methods (mean, median, or mode), the results were incessantly around that expected number with small variances.
This experiment was supposed to mimic a basic way in which drug trials are exsert, using a leukemia drug with a 5-year endurance rate of 50% as an example. Whether a trial is run on a small group, or a bigger group, calculating the statistics using the various methods can help to shape what per centum of the results occur by stochastic chance versus what percent of the survival rate is really due to the drug itself. In the long run, a larger n in each trial can help to lower the possibility of random chance, which helps to give a more clear idea closely whether a drug should be approved for use on patients, require more testing, or be scrapped all together.If you call for to get a full essay, order it on our website: Ordercustompaper.com
