Carlos Valolbona Essay

To begin, there is an experiment done by Carlos Vallbona about magnets and pain relief with the question “Can the chronic pain experienced by post polio patients be relieved by magnetic fields applied directly over an identified trigger point?” There were a couple of questions concerning the study done by Vallbona, which included: Does the data support or refute the claim that active magnets relieve pain? What is known about population (the group the collected data is intended to describe), population parameters (a value calculated using all the data from the entire population), sample (a smaller subset of the entire population, ideally one that is fairly representative of the whole population), sample statistics, and bias (in favor or against something, unfair)? How representative is the data presented for determining whether magnets actually relieve pain? Is there anything that needs to be changed to make this study more representative and …show more content…
As was seen in the active magnets data, there is more change between the the pre and post data from using active magnets than there is using the placebos. When looking only at the histograms, you could tell right away that magnets relieve pain since the change is higher with the active magnets than with the placebos. In other words, most of the people who used the placebos experienced little to no change of pain. On the contrary, many of the participants who used the active magnets experienced more change in their levels of pain. When taking a look at the range of both active magnet and placebo data, you could tell that active magnets relieve more pain since the range is ten and the range for those using placebos is five. As I’ve already mentioned, this shows that active magnets relieve more pain than placebos, but they don’t help all people because there were some participants who had no change at all, but most of them
