"A cognitive psychologist wanted to investigate the stage of moral development reached by college students. She believed that people progressed, in order, through six stages of moral reasoning, from Stage I to Stage VI. She obtained a representative sample of college students in the United States and administered an inventory to classify stage of moral development. Here are the numbers of people classified at the different stages: I = 17, II = 34, III = 78, IV = 187, V = 112, and VI = 88. Make a frequency distribution table for these data, showing frequency, cumulative frequency, percentage, and cumulative percentage."
