The term "effect" refers to a change that results from a specific cause or action. It is often used in various fields, such as science, psychology, and everyday life, to describe how one event influences another. For example, the effect of studying regularly can lead to improved grades in school. In research, understanding the effect of different variables is crucial for drawing accurate conclusions. For instance, scientists may examine the effect of a new medication on patients to determine its efficacy. By analyzing these effects, researchers can better understand relationships and make informed decisions.
