The purpose of our experiment was to test the effectiveness of different rain repellants on automotive mirrors. For the statistical analysis, we performed an ANOVA Test, and analyzed the data using descriptive analysis. We performed thirty-two different trials, each of which tested one of four different types of rain repellants. These types include a control group (clean mirror), RainX, Meijer Brand, and Rain Clear rain repellents. For our experiment, we hypothesized that if we could recreate rainfall's effects on various rain repellent treated mirrors, we would conclude that RainX rain repellant would be the most effective, and the control group would be the worst. We performed the trials by spraying a mirror with water at a consistent angle and intensity for thirty seconds and then recording the mass of the water present on the mirror at the end of the trial. At the end of testing, we concluded that our data does not support our hypothesis. Although the water repellants did protect the mirror from water build-up more effectively than the control group, there was no statistically significant difference between the effectiveness of RainX and that of the other repellents.
