|
|
Findings of nonexperimental correlational studies can be generalized to larger populations
|
|
|
Many of the phenomena of clinical interest do not lend themselves to manipulation, control, or randomization
|
|
|
Independent variables can be manipulated very precisely in correlational studies
|
|
|
To determine the best clinical practices, nurses must be aware of cause-and-effect relationships
|
Detailed explanation-1: -This is because while experimental research can provide strong evidence that changes in an independent variable cause differences in a dependent variable, nonexperimental research generally cannot.
Detailed explanation-2: -What are some reasons for using the non-experimental method to study relationships between variables? Measures variables of interest as they naturally occur, without experimenter intervention or manipulation.
Detailed explanation-3: -Non-experimental designs are used simply to answer questions about groups or about whether group differences exist. The conclusions drawn from nonexperimental research are primarily descriptive in nature. Any attempts to draw conclusions about causal relationships based on nonexperimental research are done so post hoc.
