You have been hired to develop a new study program that will increase the number of hours the average college student at KU spends studying. In order to do this, you sample 200 students from the School of Business who attend KU part-time and are currently enrolled in one of your classes. You ask 100 of these students to monitor and make note of the number of hours they spend studying each day, for a total of 10 weeks. This group functions as your control.

The other 100 students participate in your new "study program." This program uses a combination of weekly check-ins with their instructor, incentives for study time, study buddies, and study groups. This new study program group also monitors and notes the amount of time they spend studying each day throughout the 10-week class. After the ten weeks is over, you collect and analyze your data. Your results suggest that students in your new program spend significantly more time studying than those in the control group (about 12 hours a week versus 8 hours).

Determine if internal validity, reliable, sensitive and external validity apply to the experiment described above and justify your answer. Do you agree with these conclusions? How would you improve upon this study? What would you change and why?
