Answer to Question 1

ANS: B
In examining the validity of the new instrument, it is important to determine how closely the existing instruments measure the same construct as the newly developed instrument (convergent validity). Divergent validity would measure the differences in measurement, between an existing instrument and a newly-developed one. Discriminant analysis measures the difference between two related but not identical concepts. Content validity is the extent to which a measurement represents the concept being measured.

Answer to Question 2

ANS: B
Determining interrater reliability is a concern when studies include observational measurement, which is common in qualitative research. Interrater reliability values need to be reported in any study in which observational data are collected or judgments are made by two or more data gatherers. Consequently, it is used in various types of qualitative research in which data or behaviors are coded or classified.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
