Statistical tests allow us to compare the differences between treatment groups to normal variability in the dependent variable. They help us determine if the differences between groups are significant enough to conclude that the independent variable is responsible for those differences, or if they could have occurred due to chance. However, statistical tests cannot prove that the research hypothesis is true, as this would require additional evidence and confirmation from multiple studies.
