In attempting to perform the experiment, we need to understand the independent variable as well as the dependent variable. The independent variable is the cause of the phenomenon which is the emotions of ghosts or human beings in the past that died in the area of the stones. The dependent variable would be the effect of the independent variable which is the emotions etched in the physical structure of the stones. There are other variables such as the time of the recording, the presence of ghost around the stones, and the chemical makeup of the stones. All these variables will affect the two other variables. In terms of the independent variable, it is impossible to measure the feelings of human beings in the past at the exact time of occurrence. The experiment, the extraneous variable is the common chemical nature of the stones that may make the stones able to record these emotions. How can you measure that when there are various chemicals involved in different stones? In other words, if you do an experiment, there must be a physical phenomenon or effects to be measured.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
