Answer to Question 1

ANS: A

Feedback
A Instrument homogeneity is established with split-half reliability.
B Test-retest reliability establishes instrument stability.
C Interrater reliability is not a homogeneity measure.
D Alternate form or parallel form reliability is not a test of homogeneity.

Answer to Question 2

ANS: B

Feedback
A Open-ended questions elicit textual data that are content analyzed (qualitative analysis).
B The KR-20 coefficient provides estimates of homogeneity used for instruments that have a dichotomous response format.
C Cronbach's alpha coefficient provides estimates of homogeneity when instruments are scaled with ordinal responses.
D The KR-20 coefficient does not apply to this answer.

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.
