Abstract
The objectives of this research project were to examine the effects of ambient ozone on asthma prevalence. This was performed through an ecological study analyzing secondary data across all 67 Pennsylvania counties. Statistical tests used for analysis included regression analysis, chi-square analysis, and measuring the association strength and direction with gamma. Only 1.49% of the variation in asthma prevalence was explained by ozone concentration. However, when ozone concentrations are similar at the population extremities, rural residents seem to have more immunity to developing asthma than urban residents. It can be concluded that a rather weak association exists between the two variables, and there is not enough evidence to reject the null hypothesis of independence.
