Blood Pressure

  Percent difference between the start of video blood pressure and the end of video blood pressure for both the traditional and non-traditional lectures was found. Figure ___ shows these differences. From the figure, it can be seen that data for the traditional lecture have a larger range than do those for the non-traditional lecture. A two-tailed T-test was used to compare the two groups. The P-value of this T-test was 0.047, which indicates a significant difference between the two series. Participants' blood pressure decreased more during the traditional lecture than it did for the non-traditional lecture.
