Statistically Significant Results

One of the most important aspects of research findings is to ensure that the results are significant or meaningful in order to influence an appropriate course of action. In this case, the significance of the findings of a study can be described as the quality of being important.

An example of how research findings can be statistically significant but not meaningful is in the medical field. The findings of a research in the medical field can be clinically significant but not clinically important. For instance, when examining the difference between new and old therapy, the findings can be statistically significant but not meaningful. In this case, the issue under evaluation is whether the difference identified in the research is large enough to cause changes in practice.
