The graph of the classes results shows a better trend, as more alcohols were tested, so results were more accurate. I also think I didn't obtain enough evidence to justify anything. The results should have been in a straight line, the energy should have increased as the amount of crabon atoms increases. The groups results however, are quite accurate, and show an upwards trend, as the number of crabon atoms increase, so does the amount of energy. This can be seen in the graph I for the groups results Evaluating: The evidence obtained by me was not of good quality. The quality of evidence can not be expected to be too accurate, as the quailty of the experiment wasn't very high. Meaning that accurate results are not to...
