Discussion 2: Statistical Significance and Variables
Research studies often compare variables, conditions, times,
and/or groups of participants to evaluate relationships between
variables or differences between groups or times. For example,
if researchers are interested in knowing whether an intervention
produces change in the desired direction, they will want to
know whether the change is due to chance (statistical
significance) or possibly due to the intervention. In this case,
researchers could use a pre and post measurement of the same
participants on the condition being treated, or they could
compare a group of individuals who receive the intervention to
a group that does not receive the intervention. Researchers
could also compare two groups of individuals who receive
different interventions. The rigor of the research design helps
control for other factors that might account for the changes
(e.g., time, conditions, group differences in other factors, etc.).
To prepare for this Discussion, consider the concept
of statistical significance.
· Post an explanation of how the difference between statistical
significance and the true importance (clinical significance) of
the relationship between variables or the degree of difference
between groups affect your practice decision making
· Be sure to include an explanation of what statistical
significance means.
· Include an example from a quantitative study that found
statistically significant differences.
· Discuss whether the results of the study would—or should—
influence your practice as a social worker.
· Include at least 2 references and citations.
