Question

Caterpillar has been researching the idea of replacing the traditional steering mechanism on its graders with a joystick based steering mechanism. As a part of its research, it built two types of graders for testing: one that included only the steering wheel, and one that included only the joystick. Operators were then randomly assigned to use one of the two types of graders for a few days. After three days of testing, the joystick operators were much more satisfied than the steering wheel operators. This would be an example of using _______ research. Group of answer choices survey experimental observation in-depth interview

Answer 1

Experimental Research.

Step-by-step explanation:

Experimental research is a research method based on scientific approach. The research helps to understand the cause-and-effect relationshio between the two variables, namely independent and dependent. Independent variable manipulated while dependent variable remains constant.

In the given case, Caterpillar is using the experimental research method. Caterpillar is trying to understand the cause-and-effect relationship between the two variables-- the operators and two types of steering mechanisms, in which dependent variable-- the operators, remains constant, and steering mechanisms is manipulated.

Thus the experimental research method is the correct answer.
