Cell Phone Radiation Essay

Since the introduction of the cellphone to the technological world has occurred, more and more people around the world have been keeping their devices close to their heart. People are constantly using their device to do multiple activities a days, whether it is using it for simply calling or texting a friend or family member, browsing the internet to stay connected to the rest of the world, or entertaining you by allowing you to watch videos or play high graphic games. Whatever the use, cell phones have come in handy in almost every situation we confront in life. However, there is concern that the over usage of cell phones may increase the chance of obtaining cancer over a person’s lifetime. The constant radiation emitted from the device …show more content…
The goal of this article is to shed some light on this issue and to assuage people’s fear of cell phone radiation causing cancer. Like stated before, the article is against people abandoning their cellular device due to cancer risks, because so far, there is simply not enough evidence that it does indeed cause cancer (Loria, 2016). The article references an experimental study conducted by the US National Toxicology Program. The research question of the experiment was whether or not excessive device radiation on rats can significantly raise their chances of obtaining cancer compared to rats that are not exposed to radiation. Therefore, for this study, the independent variables were the two groups of rats: those that were exposed to full body radiation for nine hours a day from birth to about two years of age, and the control group where rats were not exposed to cell phone radiation from birth to two years of age. The dependent variable is the chance of developing brain cancer due to exposure to radiation or not. The population that is being tested in this experiment is the entire rat population, where rats were randomly obtained to be used in the study. The sampling strategy is not specified by the article but is most likely a random sample of rats to be used …show more content…
This test was utilized to determine if the two sets of data, rats that underwent radiation and rats that did not, were significantly different from each other. Also, both the populations’ mean and population variance was unknown for the experiment, which implies that an Independent Student’s T test must be used. The first step of NHST is to state the null and alternate hypothesis and decide on whether or not he experiment is one tailed or two tailed. A one tail test was used for this experiment because it was testing if an exposure increased the likelihood of obtaining cancer. If it were a two tailed test, then the experiment would only test to see if there was a difference in the likelihood of getting cancer or not, whether it be an increase or a decrease. After establishing if the test is one tailed or two tailed, a null and alternate hypothesis must be stated. The null hypothesis states that there is no difference in the means of the two groups, where the mean of group one is less than or equal to the mean of group two and any difference is due to chance. The alternate hypothesis makes the test exhaustive and states that the mean of group two is greater than the mean of group one. Group two will be made the rats that are tested under radiation for nine hours every day until they reach the age of two. The next step of NHST is to set the criterion. Setting the criterion involves
