The average time the participants were able to hold a weight at 90 degrees varied between music and non-music is displayed by figure 4. Each participant is listened along the X axis and the time they maintained the 90 degree angle is shown in the Y axis under both the music and non-music condition. Five of the eight individuals experiences an increase in time when listening to music while the other three did not. Those who listened to music had an average of 134 seconds and those who did not listen to music had an average of 78.25 seconds. However, the standard deviation of participants who listened to music was much higher (131) than those who did not listen to music (41.04). A T-test was preformed and indicated that there was a significant difference (P value less then 0.05) between the duration of holding a weight at 90 degrees with motivational music and when listening to no music with a 95% confidence interval.
