Video - Relative and absolute risk

Risk is the probability of an event occurring, for example, the risk of being struck by lightning. Absolute risk refers to the actual probability of an outcome occurring in a specific group regardless of any other factors. In this case, it would be the chance of being struck by lightning. Relative risk on the other hand, compares the risk of an outcome between exposed and unexposed groups. In this case, it would be the risk of being struck by lightning when flying a kite in a storm, versus when sitting still in a house.
