The manager of a nuclear power plant defended the claim that the plant was safe by revealing its rate of injury for current workers: Support only 3.2 injuries per 200,000 hours of work, Support a rate less than half the national average for all industrial plants. ███ ███████ ███████ █████ ██████████ ██ ███ ████████ ██ ███ ████ ████████ ██████ ███ █████ ███ █████ ████ ████ █████ ██████ █████ ███ █████████ █████ █████
The manager concludes that the nuclear plant is safer than most other plants where the plant’s employees could work, judging by the number of injuries. As evidence, the manager says that the nuclear plant’s rate of injuries for current workers is less than half the national average for industrial plants.
Because the manager's conclusion is explicitly limited to just the number of injuries, the magnitude of each individual injury isn't important. However, the manager still assumes that the rate of injuries for current workers is representative of overall injuries. It could be that injuries appear later in life once employment has finished, or that injuries are under-reported.
