Drews et al.2008) manipulated driving conditions i.e., driving while talking to a friend on the cell phone and driving while talking to a friend in the car) to see if this influenced the number of driving errors committed.Participants completed the task on a driving simulator.In this design, the driving condition served as the __________.
A)measure of ecological validity.
B)dependent variable.
C)independent variable.
D)measure of reliability.

Quizplus · Accepted Answer

The driving condition is being manipulated by the researchers, so it is the independent variable. The dependent variable would be the number of driving errors committed, which is being measured in response to the manipulated driving condition. The other options (measure of ecological validity and measure of reliability) do not apply to this type of experimental design.
