Using data to compare a sample to the whole population or another targeted sample of people can help researchers make predictions about future behavior or phenomena. Comparisons and predictions such as these can answer research questions and can make an argument or statement more persuasive. When there are two groups to compare, tools such as the one-sample t-test and the two-sample t-test allow researchers to make such predictions and comparisons.
