1. The Centers for Disease Control and Prevention, in a survey of teenagers, asked the subjects if they were sexually active. Those who said "Yes" were then asked, "How old were you when you had sexual intercourse for the first time?" Should consent of parents be required to ask minors about sex, drugs, and other such issues, or is consent of the minors themselves enough? Give reasons for your opinion.

2. The "Post a Statistic" discussion question will appear in each module. I want each of you to find a current statistic that interests you from a newspaper, magazine, website, etc. and post it here. You should cite where you got it from so others can go to it and also explain why you found that statistic interesting. After posting of the statistics, I would like to see some discussion on them or supplemental information.

3.Talk about the concerns of the placebo effect and why it is important to account for it in experimentation. Provide examples of the placebo effect in action.

4.Refusals, Nonadherers, and Dropouts are problems in experimentation. Talk about what each is and give examples of what problems can occur because of them.
