Some similarities of our data compared to other groups data would be that everyone seemed to have unusable data when it came to the hand soap, iodine, and hydrogen peroxide. This concludes that all of these disinfectants are useful in killing all bacteria or that the paper discs were simply too wet when they were put onto the agar.
