Worm Lab

     For this experiment, we observed the California Black Worm to determine its pulse rate when put into different solutions. We split up into our lab groups to time the pulse rate of the worms per minute, (5 times each), and then we came back together as a class to exchange our data. Based on the data alone, I calculated the average of pulse rates for each silution, in order to figure out if each solution was the normal, stimulant, or depressant. I began by calculating the average of each solution for each group, until I realized that some groups' data consisted of no [none] pulse rates. Therefore, I combined all the groups data for each solution instead. It appears that Solution A had the highest average, making it the stimulant. Next comes Solution C, which leaves Solution B as the depressant. I decided to take the average because the experiment was conducted inaccurately, knowing that each group had a different approach of completing this experiment, and there is plenty of room for errors when doing a lab. Statistically speaking, the average reflects the inaccuracy of the experiment overall, since calculating involved rounding as opposed to an exact number.
