At least three seismic stations are needed to compare results and determine the epicenter of an earthquake using the method of triangulation. By measuring the arrival times of seismic waves at different stations, scientists can pinpoint the epicenter where the waves intersect.
In an experiment, the standard used to compare with the outcome is called the control group. The control group is a group that is not exposed to the experimental treatment and is used as a baseline for comparison to determine the effects of the treatment on the experimental group.
