Question
SUBJECT: EPIDEMIOLOGY
Calculate the rate difference and provide an interpretation of the result: You conduct a study to assess the association of traffic accidents to the use of cellular phones while driving. Your study reveals that per 10,000 miles, the incidence of traffic accidents for people that were using their cellular phones is 11.1; and the incidence of accidents for people not using their cellular phones is 8.6. Detrermine the difference between accident rates for people that were driving and using their cellular phone versus those that were not using their phone while driving. Then write a paragraph or two explaining your findings or results.
Explanation / Answer
Risk Difference = (number of people having accidents using their cell phones)/(total number of persons) - (number of people having accidents without using cell phones)/(total number of person)
=> 11/(11+1) - 8/(8+6)
=> 11/12 - 8/14
=> 11/12 - 4/7
=> (11 * 7 - 12*4)/84
=> 29/84
According to the results, the people using cell phone at the time of driving are more prone to car accidents as compard to the people who are driving without using cell phones, the mobile phones should not be allowed at the time of driving and people should ensure the usage of bluetooth headsets and Govt should also start charging fine if someone is saw using phone while driving
