Quizplus · Accepted Answer

In order to know whether gang violence is decreasing, we need a baseline measurement to compare and evaluate any changes. A control group and experimental group are typically used in experiments, while a chi-square test is a statistical method used to analyze categorical data. None of these options directly relate to measuring a decrease in gang violence in a community.
