Question

In a laboratory, smokers are asked to "drive" using a computerized driving simulator equipped with a stick shift and a gas pedal. the object is to maximize the distance covered by driving as fast as possible on a winding road while avoiding rear-end collisions. some of the participants smoke a real cigarette immediately before climbing into the driver's seat. others smoke a fake cigarette without nicotine. you are interested in comparing how many collisions the two groups have. in this study, the dependent variable is ________.

Answer 1

In research studies, when you execute scientific experiments, you always have the independent and dependent variables. Dependent variables are the parameters you want to measure or investigate. Independent variable, on the other hand, are parameters or events that you control or set. In this case, the dependent variable is the amount of collisions made by the two groups.
