Purpose of study- Determine the relationship of the death of a driver to marital status, Determine if there is a relationship between survival of a drunk driver in a car accident with a fatality and marital status.
Sampling-Total of drivers who were reported as driving drunk through the National Highway Traffic Safety Administration, involved in a car accident with a fatality in the 50 states in 1995. Percentage of adults in the 50 states, who identified their marital status as married or never been married/single on the 1995 Behavioral Risk Factor Surveillance System (BRFSS) survey.
Accuracy: since data was not gathered first hand, its absolute accuracy can not been assured
Data Sources: Combination of Journal Articles, governmental websites
Ethical Concerns: Data from the BRFSS was submitted voluntarily, reports of drunk drivers behavior reported via National Highway Traffic Safety Administration.
Representativeness of Sample: Percentages of population of the 50 states chosen by either response to BRFSS or involvement in a car accident with a fatality, while being determined by blood test, to be legally drunk.
Test used: Students T test, ANOVA
Findings: 3 of the 4 hypotheses tested, yielded statistically significant results. The first hypothesis, n=50, r=-.33, t = -2.41, p .05, significant results and indicates an inverse relationship between married adults & the drunk driver killed in a car accident. The results of the second hypothesis were significant, n = 50, r = .46, t = .35, p .01, demonstrated a relationship between married adults and drunk drivers who survived car accidents with a fatality. The third hypothesis, exploring the relationship between drunk drivers who were killed in car accidents and adults who had never been married, n = 50, r = .15, t = 1.07, not statistically significant. The fourth hypothesis, n = 50, r = 2.76, t = -2.42, p .05 level, statistically significant, and showed an inverse relationship between adults who had never been married & drunk drivers who survived car accidents with a fatality.
