After I was finished with both the CD and cassette, I asked if the person could identify which one was the CD and which was the cassette. When they answered me, I recorded my data. This is the information that I have found out through my experiment. A CD is much clearer than a cassette. Cassettes are slower and not as clear.
People can clearly tell the difference between the two.
My data show that my hypothesis was correct. My hypothesis was correct. I was correct because all of the experiments I completed proved that people could definitely hear a clear difference. I think I could definitely improve my experiment by testing a lot more people, keeping the music on for a longer period of time, and using different types of music to see if the type of music has any affect on the way that you hear it. What I did wrong was use a different CD then cassette.
