• I did not consider some control variables before undertaking the experiment. The earphones/headphones were not the same manufacturer for every person, and should have been kept the same (though most people used the same brand). This may affect their performance as most headphones have different mechanical features which cause different outputs of sound.
• Furthermore, the volume was adjusted to suit the needs of each individual. I feel as though this should have also been controlled, as a louder volume as opposed to a quieter volume will definitely affect one's performance.
• The age group was very limited, as most participants were 16, 17 and 18. Results may have been different if older age groups participated, but with the experiment taking up a lot of time, it is restricted to who I could ask. Randomly selecting participants would not work because it is required to take up at least 2 days of their time, which would have been unlikely.
• The choice of songs used could have been better in my opinion; using 3 remixes and 1 from scratch is unbalanced. Unfortunately, my laptop was damaged and I was unable to create anything from May to the end of July, and the experiment was conducted during mid-July. I feel as if using 2 songs from scratch, such as 8PM, 9PM or 10PM, would have been ideal
