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 independent variable is _____________________.

Explanation:

A variable is something we are attempting to measure. The independent variable is the one that stands alone and isn't altered by other intervening variables. When analizing the relationship between variables, we want to see whether or not the independent variable produces any modification in the dependent variables. A dependent variable is the one that depends on other factors.
