Answer to Question 1

ANS: A
In a correctly designed research study, the methods of measurement match or are appropriate to the research purpose.
In a correctly designed research study, the research question can be addressed with the design chosen.
In a correctly designed research study, the researcher is capable of conducting the study.
In a correctly designed research study, the plans for data analysis are reasonable and match the study questions.

Answer to Question 2

ANS: A
A good researcher needs to select an instrument with high validity and reliability. Although a study might determine that the one indicated here works well to measure happiness, that would need to be determined. In critiquing the study, this would be a major flaw unless the researcher reports on the validity of the instrument for this purpose. Questionnaires cannot be applied to different variables without testing.
The representativeness of the population is not of concern in regard to the instrument selected.
Scores on the instrument are not of concern if the instrument is not valid.
Items B and C are not correct, making this choice incorrect also.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
