How does a comparative descriptive design differ from a typical descriptive design?
a. It compares statistics between the current time and an earlier time, whereas the typical descriptive design focuses on only one time period.
b. It compares a number of variables and examines the relationship between them, whereas a typical descriptive design never does this.
c. It differs in name only; both have the same design.
d. It describes data from two different groups, whereas a typical descriptive design focuses on a single group.
ANS: D
The commonly used descriptive study design examines characteristics of a single sample. It identifies a phenomenon of interest and the variables within the phenomenon, develops conceptual and operational definitions of the variables, and describes the variables. The comparative descriptive design examines and describes differences in variables in two or more groups that occur naturally in the setting. Descriptive statistics and inferential statistical analyses may be used to examine differences between or among groups.
