Pulse Stimulant

In my lab experiment, it was concluded that the Group B had the solution of the stimulant. Group A, has the normal solution. And, Group C has the depressant effects. 

As a whole, the class had on average the answer as B for being the depressant. 

My lab group had come up with group A's results at 28, 28, 31, 33, and 27. Group B's results would be 33, 38, 34, 37, and 33. Group C had: 35, 24, 31, 29, and 32. Group A had an average of 24. Group B had an average of 28.2. Group C had an average of 23.8.

Based off these results, it was concluded that C was the depressant because the pulse rate was vastly lower than the rest.
