A polygraph is a common instrument of measurement to calculate and document physiological aspects such as respiration rate, electrodermal activity, and heart rate. The relevant uses of measuring respiration rate as well as heart rate are quite common in a wide variety of applications. However, electrodermal activity and the galvanic skin response are not commonly measured things in places such as the medical field, or education. Electrodermal activity (EDA) refers to the variation of the electrical properties of the skin in response to sweat secretion. (Benedek et al., 2010) Collecting this information is relevant in applications because of the use of testing emotional effects on physiological responses. According to Mark Handler and other authors of their journal An EDA Primer for Polygraph Examiners the physiological response to emotional catalysts that stimulate change cause a restriction in vascular flow within the body. The purpose of the change to restrict blood flow

Table 1 shows the quantitative results of the heart rate in BPM’s, while Figure 1 also displays the qualitative data of song tempo speed. Both show the correlation between song tempo with heart rate.
Discussion:
Both in Table 1 and Figure 1 the results showed the parallel increase and decrease in tempo of the music with the heart rate. Thus supporting the previously stated hypothesis that an increase in music tempo increased heart rate and the prediction that if the tempo of music was increased then the subjects heart rate would increase as well. An alternative hypothesis could be the null. Perhaps that the tempo did not have an effect on heart rate. This alternative hypothesis would not be supported since the results did show a significant effect and correlations between heart rate and variant music
