Question

CM Chapter 3: Numerical Descriptions of Data To determine if Reiki is an effective method for treating pain, a pilot study was carried out where a certified second-degree Reiki therapist provided treatment on volunteers. Pain was measured using a visual analogue scale (VAS) immediately before and after the Reiki treatment (Olson & Hanson, 1997). Graph #3.3.9 is of box-and-whiskers plots that were created of the before and after VAS ratings. Discuss any conclusions you can make from the graphs. Graph #3.3.9: Box-and-Whiskers Plot of Pain Using Reiki VAS of Subjects Before and After Reiki Treatment for Pain After Before 0 1 2 3 4 5 6 7 8 9 10

Explanation / Answer

Answer:

Here, we have to compare the two box plots for the variable visual analogue scale (VAS). From given two box-plots for visual analogue scale (VAS), it is observed that the average visual analogue scale (VAS) before the Reiki treatment is given as approximately 4 and it is higher than the average visual analogue scale (VAS) after the Reiki treatment. The spread for the VAS before the Reiki treatment is more than the spread for the VAS after the Reiki treatment. Both distributions are right-skewed in nature. In simple words, we can say that the pain scale is lower after the use of Reiki treatment. This means the Reiki treatment is effective for lowering your pains.
