An example of non-experimental research is measuring the number of traffic fatalities involving cell phone use over a given period, such as the past year. In this scenario, researchers merely record naturally occurring data and do not actively manipulate whether drivers use cell phones. While this observational approach allows researchers to describe patterns and make predictions about traffic accidents, the lack of manipulation means they cannot definitively conclude that cell phone use causes traffic fatalities.

Example of Non-Experimental Research: Traffic Fatalities

In a non-experimental study measuring traffic fatalities involving cell phone use by recording naturally occurring data, why are researchers unable to definitively conclude that cell phone use causes the fatalities?
