A18. The following appeared in a proposal from the sheriff of Adams County. “Last year a course in driver’s education became a requirement for graduation for all students at the Adams County High School, and the board of education purchased 10 new cars to provide students in the classes with on-the-road driving experience. Nevertheless, the number of teenage drivers involved in traffic accidents here in Adams County has increased by 200 percent this year, and officers from the sheriff’s department have cited a record high number of teenagers for violations of traffic laws. Since the high school driver’s education classes have been so ineffective in improving traffic safety, we should no longer require them and should spend our limited funds on other programs.” 1no causal relationship 2other factors should be considered and ruled out 3Therefore, there is no sufficient evidence to support the suggestion to stop the program.
1)most drivers in the incresead traffic accidents are the teenagers who are younger than the students due to graduation year,so the former ones do not attend the course in driver’s education;
2)increased traffic accidents may attibute to the unfavorably abnormal weather conditions in this year;
