What type of research design is used in the research study described in this statement? "To detect differences in the knowledge levels of older adults regarding osteoporosis, subjects were randomly assigned to a control group, which received printed materials, and an experimental group, which received computerized instruction. The same pretest and posttest were administered to all subjects."
Longitudinal.
Quasi-experimental.
Descriptive.
Experimental.
The Correct Answer is D
A. Longitudinal studies involve observing the same subjects over an extended period to assess changes over time. The study described involves comparing two groups (control and experimental) at one point in time, rather than observing changes in the same subjects over time.
B. Quasi-experimental studies resemble experimental designs but lack random assignment to groups or lack control over certain variables. The study described involves random assignment to groups (control and experimental), making it an experimental design rather than quasi-experimental.
C. Descriptive studies involve observing and describing phenomena without manipulating variables or testing hypotheses. The study described involves manipulation of the independent variable (instruction type) and comparison of outcomes, making it experimental rather than descriptive.
D. Experimental studies involve manipulating an independent variable to observe its effect on a dependent variable while controlling for other variables. The study described involves randomly assigning subjects to control and experimental groups, manipulating the type of instruction, and comparing knowledge levels before and after the intervention, indicating an experimental design.
