Chapter2:LiteratureReview

Previousstudieshaveexaminedtherelationshipbetweenageandcaraccidents,withmixedresults.Somestudieshavefoundthatolderdriversaremorelikelytobeinvolvedinaccidents,whileothershavefoundnosignificantrelationshipbetweenageandaccidents.OnestudyfromtheNationalHighwayTrafficSafetyAdministration(NHTSA)foundthatdriversovertheageof80hadthehighestrateoffatalcrashespermiledriven.

Statisticalmethodsusedinpreviousstudieshaveincludedregressionanalysis,logisticregression,andanalysisofvariance(ANOVA).Thesemethodsallowedresearcherstoanalyzethedataandidentifyanysignificantrelationshipsbetweenageandcaraccidents.
