Data Set 19: Car Crash Tests Data are from 21 cars in crash tests (first five rows shown here). The same cars are used in Data Set 20. The data are measurements from cars crashed into a fixed barrier at 35 mi/h with a crash test dummy in the driver's seat. HIC is a measurement of a standard "head injury criterion," CHEST is chest deceleration (in g, where g is a force of gravity), FEMURL is the measured load on the left femur (in lb), FEMUR R is the measured load on the right femur (in lb), TTI is a measurement of the side thoracic trauma index, and PELVIS is pelvis deceleration (ing, where g is a force of gravity). Data are from the National Highway Traffic Safety Administration.
