Conclusion and how I came to it: I postulate that solution A is the water, solution B is the depressant, and solution C is the stimulant. I came to that conclusion because in the data in chose to look at, which was my groups, Mel's group, Kyle's group, and Shy's group, solution A was not the slowest pulse rate but it was not the fastest either. Solution C was the fastest and Solution B was slightly slower than solution A.
Method: First, I looked at all the data from all the groups and crossed out all the outliers, or the numbers that seemed extremely small, large, or that were not consistent with the majority of the other groups data. However, solution A of Shy's group data looks like an outlier but I did not cross it out for consistency because I used her other two solutions.
Then I took each groups average of each solution and recorded it. I also Added all the groups averages for each solution. However, I did not add solution A of Shy's group data because it would skew the results since the number is so small.
Like so: (Mel's first one is 24.8 sorry for the messy handwriting!)
When looking at the data I put together, I observed that in every groups but shy data solution B had the slowest heart beat and solution C had the fastest, which means solution C is the stimulant and solution B is the depressant. Since solution A was not the fastest or slowest, I thought that one was water.
