the effects of marijuana on studentâs heart rate

An experimenter was interested in seeing the effects of marijuana on studentâs heart rate. The experimenter randomly selected 100 students from SUCO campus and ran double-blind experiment. 50 of the students received .5 g of marijuana, and the other 50 received a placebo. The 50 students who received the placebo were separated and put in a room with dark walls, while the other group remained outside on the grass. The experimenter then asked the students to rate their heart rate on a 1-7 Likert scale. 7 meaning their heart rate is at its highest. He also performed a physiological test on the students to test their heart rate. 

 

What could be considered extraneous in this experiment?
