Praxis 5005 Practice Question
Which of the following was the dependent variable in this investigation?
Correct Answer: B
Rationale: In this investigation, the dependent variable is the flight distance (B), as it is the outcome being measured to assess the effect of the independent variable. The wingspan (A) is likely a characteristic of the subjects being tested, not a variable being manipulated or measured in response to changes. The stopwatch (C) and tape measure (D) are tools used for measurement, not variables in the experiment. Therefore, only flight distance reflects the response to the experimental conditions, making it the dependent variable.
