Question

1. to test a new voice feature in a cockpit design a flight simulator was used. the simulator was programmed to give visual only readings of flight information, or to give visual and voice readings of the flight information. all test pilots were put through a simulation emergency landing procedure, but were randomly assigned to the visual only, or visual and voice conditions. flight experts rated each pilots performance in the simulator on a scale from 1(very poor) to 10 (excellent). what is the: independent variable: dependent variable: experimental group: control group:

Explanation:

The independent variable is what is manipulated. Here, it's the type of flight - information reading (visual only or visual and voice). The dependent variable is what is measured, which is the pilots' performance rating. The experimental group receives the new treatment (visual and voice), and the control group gets the standard or no - treatment (visual only).

Answer:

Independent variable: Type of flight - information reading (visual only or visual and voice)
Dependent variable: Pilots' performance rating
Experimental group: Pilots in the visual and voice condition
Control group: Pilots in the visual only condition
