Question

The FAA is trying to determine if the size of airplane seats can be safely reduced. To test this, the FAA simulates an emergency onboard an airplane and measures the number of seconds it takes to disembark the airplane. To make sure it is only the size of the seat and not any other variable that is influencing the time it takes to disembark the airplane, the FAA sets up the same emergency in a 737 with a seat width of 19 inches and an identical 737 with a seat width of 17 inches. Each airplane is kept at half occupancy, the passengers are all young and fit and know that they are in a simulated emergency and the goal is to disembark as quickly as possible, no luggage is allowed on board, and the lights are kept on. What do you think of the FAA's methods? Be sure to define and use internal validity and external validity in your answer.

Answer 1

The FAA's methods can be really effective in determining the solutions to the test.It is because they are trying to find the factors and then analyse whether there are any side effects of it.Also, the passengers are young and they will have the capacity to cope up with the problem.FAA's method can be defined as ''Analysing and solving the problem''.

The FAA will be getting internal and external support as they have no risk of having old passengers and also they are analysing the factors for the experiment.
