First the outliers of the data were not considered in the calculations. Taking the average of day 1 and day two of all three batches (A,B,C) and then combining the averages of both the days. This resulted of having an overall average of A: 35.45 , B: 28.15, and C: 37.23. With this data and these calculations it seems that Batch A of the worms was normal and had no kind of substances added to alter the worms pulse. On the other hand Batch B had a much lower average pulse compared to the other batches ,so this was the batch with the depressant. And finally Batch C had an average pulse of 37.23 making this the Batch with the stimulant which affected the worms an having a higher pulse rate than the other batches.
