Suppose that you work for a company that has just created a program designed to teach reading to elementary students. Discuss how an experiment could be created to see whether this product is superior to other reading programs. Develop a hypothesis, label the independent and dependent variables, discuss what the experimental and control groups are doing in this study, and decide who (and how many) participants are needed. Be sure to discuss random sampling and random assignment.
