Question

You are interested in evaluating the effectiveness of three different education programs on caffeine consumption in young adults, age 18-24 years, who report that they drink at least one cup of coffee per day. You have a volunteer group of 30 subjects, and randomly assign each to one of the three education programs. Immediately after completion of the study, you determine how many have changed their consumption of caffeine (measured as change/ no change). You re-interview the participants six months after completion of the program to determine if there has been a change in drinking habits. Define a research question, independent variable(s), dependent variable, level of measurement, and controlled variables.
