To determine which of the different solutions (A,B,C) was which I applied my new knowledge from statistics. With the data we collected in class on Friday, I created three different
stemplots for substance A, B and C.
When I did that, I found that A had the highest values for number in the tens (eg. 11, 12 ...). This led me to conclude that Substance A was the depressant since the heart beat counts were so low.
When I created the stemplots for substances B and C, I found that they both had the highest values for numbers in the twenties (eg. 21, 22 ...). From here I concluded that substance C was the stimulant because it had more values in the 30s than substance be did. I also based my conclusion on my observations during the lab. When I was counting the heart beats of the worms in substance C I can remember that before I was able to get the worms out they were all almost fighting each other and all intertwined into a ball.
Therefore, this means that substance B is the water, because during the lab I also observed that these worms seemed to just swim calmly.
