Question

a team of researchers is testing the effectiveness of a new hpv vaccine. they randomly divide the subjects into two groups. group 1 receives existing hpv vaccine, and group 2 receives new hpv vaccine. the patients were told which group they were in. which is the treatment group? group 1 group 2 neither group which is the control group (if there is one)? group 1 group 2 no control group is this study blind, double blind, or neither? blind double - blind neither which best describes this research? survey placebo controlled experiment controlled experiment experiment

Explanation:

1. The treatment group in an experiment is the one receiving the new or experimental treatment. Here, Group 2 is getting the new HPV vaccine, so it is the treatment group.
2. The control group is the one that serves as a baseline for comparison. Group 1, receiving the existing HPV vaccine, acts as the control group.
3. In a blind study, participants do not know which group they are in. In a double - blind study, neither the participants nor the researchers know. Since the patients were told which group they were in, this study is neither blind nor double - blind.
4. This is a controlled experiment as there is a control group (Group 1) and a treatment group (Group 2) to compare the effectiveness of the new vaccine against the existing one. It is not a placebo - controlled experiment as there is no placebo involved, and it is not just a survey as it involves an intervention (vaccine administration).

Answer:

1. Group 2
2. Group 1
3. Neither
4. Controlled Experiment
