Answer to Question 1

ANS: D
An instrument is selected to measure a specific variable in a study. Data generated with an instrument are at the nominal, ordinal, interval, or ratio level of measurement. The level of measurement, with nominal being the lowest form of measurement and ratio being the highest, determines the type of statistical analyses that you can perform on the data.

Answer to Question 2

ANS: D
Subjects' knowledge of a study could influence their behavior and possibly alter the research outcomes. This threatens the validity or accuracy of the study design. An example of this type of threat to design validity is the Hawthorne effect, which was identified during the classic experiment at the Hawthorne plant of the Western Electric Company during the 1920s and 1930s. The employees at this plant exhibited a particular psychological response when they became research participants: they changed their behavior simply because they were subjects in a study, not because of the research treatment.
